Furniture Knobs & Handles Compatible with IKEA Hemnes: Hole Spacing 32mm System

May 2, 2026

System 32 is the international standard in furniture construction, in which the hole spacing of furniture handles, hinges, and shelf supports is always a multiple of 32 mm.

Anyone wishing to modify or repair existing pieces of furniture such as the widespread IKEA Hemnes series usually relies on fittings that correspond precisely to this industrial grid. Replacing furniture knobs or bow handles requires a basic technical understanding of dimensions, thread types, and material properties. This guide provides joiners, fitters, and skilled craftspeople with the necessary specifications to ensure the compatibility of replacement handles with existing drill holes and to carry out the installation professionally.

The Key Buying Criteria for Furniture Fittings

When selecting handles for front panels and drawers, hard facts determine the accuracy of fit. Visual aspects are secondary to technical feasibility, particularly when no new holes are to be drilled into the furniture front.

Hole Spacing and Overall Length

The hole spacing (also referred to as hole centres) is the decisive dimension. It is measured exactly from the centre of one drill hole to the centre of the other drill hole. Since the furniture industry manufactures according to System 32, standardised values are found here. Typical spacings for standard chests of drawers and cabinets are 64 mm, 96 mm, and 128 mm. The overall length of the handle is always greater than the hole spacing and must be taken into account during planning so that the handle does not strike adjacent carcasses or walls when the door is opened.

Thread and Screw Length

Furniture handles are almost without exception fastened with an M4 machine screw (metric ISO thread). The required screw length is calculated from the front thickness plus the thread engagement depth into the handle (typically 4 mm - 5 mm). For a standard MDF or chipboard front with a thickness of 16 mm to 19 mm, M4 screws with a length of 22 mm to 25 mm are typically used. For framed doors or solid wood fronts, such as those sometimes found on the Hemnes series, the material thickness at the exact drilling point must be determined using a vernier calliper.

Material and Surface Finishing

The durability of a fitting depends on the base material. Frequently, Zamak (a zinc-aluminium-magnesium-copper alloy) is used in die casting. It provides high dimensional stability and can be electroplated effectively. Alternatives include solid stainless steel, which is particularly corrosion-resistant, or aluminium, which stands out for its low weight. Surfaces are either anodised, powder-coated, or electroplated to ensure scratch resistance and resistance to hand perspiration.

Types and Options at a Glance

Depending on the width of the drawer or the height of the cabinet door, different handle types are used, which differ in their force transmission onto the front.

Furniture knobs (single-hole mounting): Fixed with just one screw. They are suitable for narrow drawers or lightweight furniture doors. Because they can twist if insufficiently tightened, high-quality models feature small anti-twist pins on the reverse side.
Bow handles: The classic two-hole handle. Due to their curved shape, they offer ample room for the hand. They distribute the pulling force across two points, which is essential for heavier drawers.
Bar handles (rail handles): Often manufactured from cylindrical material. The ends extend past the mounting pillars. They are frequently mounted in kitchens or on large wardrobes.
Profile handles (edge pull handles): These are not drilled frontally through the door, but are fitted over the top or side door edge and screwed from behind. They require an adequate gap between the front and the carcass (usually 2 mm - 3 mm).

Which Handle for Which Application? – A Decision Guide

The choice of dimensions must correspond to the mechanical load and the geometry of the piece of furniture.

If you are equipping narrow drawers (width under 400 mm) or lightweight top cupboards, choose a furniture knob or Furniture handles 32 mm. The low pulling force when opening requires no wide leverage.

If you are outfitting standard chests of drawers (such as a typical IKEA Hemnes with a width of 800 mm to 1600 mm), Furniture handles 96 mm or Furniture handles 128 mm are the most technically sensible choice. These dimensions harmonise with the proportions of medium-height fronts and distribute the pulling force optimally, preventing the drawer front from bending under a central pull.

If you are fitting heavy full-extension drawers, for instance for cookware or tools, the high weight (often 30 kg to 50 kg load capacity per drawer) requires a broad handle. Opt for Furniture handles 160mm or Furniture handles 192mm in this case. A wider handle forces the user to position their hand more centrally, preventing jamming of the ball bearing runner or undermount runner when pulling out.

Regarding material and surface technology: For humid rooms or kitchen environments where aggressive cleaning agents are used, Furniture handles silver made from anodised aluminium or stainless steel are the most durable solution. For living room furniture in a Scandinavian style, where a low-reflection texture is required, powder-coated Furniture handles matt black are recommended.

Installation Note and Fitting

Professional replacement or new installation of handles requires precision. An accurately aligned drilling template acts during assembly like the escapement in clockwork – it sets the unyielding rhythm for all subsequent steps and prevents asymmetrical hole patterns.

Required tools:

Cordless drill/driver
Wood drill bit with centring point (Ø 4.5 mm or 5.0 mm)
Pozi or Phillips screwdriver (PZ2 or PH2, depending on the screw head)
Vernier calliper and folding rule
Backing block (scrap piece of chipboard)
G-clamp

Step-by-step instructions:

Measure and mark: Determine the centre of the front. Mark the desired hole spacing (e.g. 128 mm) symmetrically to the centre line. Use a drilling template to transfer the height precisely from the top edge.
Protect against breakout: Secure the backing block tightly to the rear of the front using the G-clamp, positioned exactly behind the marked drill points. This prevents tearing of the melamine coating or veneer when the drill bit breaks through.
Drill: Position the wood drill bit at a 90° angle. A drill bit diameter of 4.5 mm or 5.0 mm gives the 4 mm screw minimal clearance to compensate for tolerances of 0.5 mm to 1.0 mm during fastening.
Fasten: Insert the M4 screws from the rear through the drill hole. Place the handle in position and tighten the screws by hand initially to avoid cross-threading in the screw thread. Then tighten the screws hand-tight with a manual screwdriver. Avoid using the cordless screwdriver for the final turn to prevent stripping the thread in the Zamak or aluminium handle.

FAQ – Frequently Asked Technical Questions

How do I correctly measure the hole spacing of an existing handle? The hole spacing is always measured from the centre of one screw to the centre of the other screw. Remove the handle and measure the distance between the drill holes on the front using a vernier calliper or a precise rule. Typical dimensions are 96 mm, 128 mm, or 160 mm.

Are third-party handles compatible with IKEA Hemnes? Yes. The furniture industry, including IKEA, manufactures according to System 32. If your Hemnes chest of drawers already has drill holes, measure the distance. If this corresponds to a standard dimension (e.g. 96 mm), you can fit any standardised fitting. For individual knobs, you can use any 1-hole knob with an M4 thread.

Which screws do I need for installation? As standard, M4 pan head screws are used. The length must match the thickness of the furniture front plus approx. 4 mm to 5 mm of thread engagement depth into the handle. For an 18 mm thick front, you consequently require a screw with a length of 22 mm to 24 mm.

Can I replace a furniture knob with a bow handle? Technically, this is possible. You use the existing hole of the knob as the first mounting point. From this point, measure the hole centres of the new handle (e.g. 128 mm) horizontally or vertically and drill a second hole. Ensure exact alignment parallel to the door edge.

Why do my furniture handles loosen over time? This frequently happens with heavily used drawers due to micro-vibrations. The M4 screw loses its preload force. A drop of low-strength threadlocker (thread adhesive) applied to the front threads of the screw before tightening, or the use of matching washers or spring washers on the inside of the front, will resolve this.
