DIYUK Hex Nuts DIN 934, Zinc Plated BZP Finish, Steel Metric Coarse Thread, M2.5 M3 M4 M5 M6 M8 M10 M12 M14 M16 M20 M24 M30 M36, Packs of 1 to 100

DIYUK hex nuts manufactured to DIN 934, in 18 sizes from M2.5 up to M36, each in packs of 1, 10, 20, 50 or 100. Their standard height and hexagonal shape give a secure, stable connection, and the DIN 934 hexagon nut is one of the most widely used and versatile fastening elements, compatible with a wide range of metric bolts and threaded rods.

The hexagon body carries a bright zinc-plated (BZP) finish, giving a bright silver appearance and general-purpose corrosion resistance. Every size features standard right-hand metric coarse threading, machined to DIN 934 dimensions, so each nut mates securely with any correctly sized metric bolt, screw or threaded rod. Fitting and removal need nothing more specialist than a standard open-end or socket spanner sized to the width across flats given in the specification table below.

Typical Applications

• Workshop benches and fixtures: permanent or semi-permanent assemblies.
• General mechanical assemblies: mates with any correctly sized metric bolt, screw or threaded rod.
• Mechanical engineering and machine building: a standard DIN 934 nut that mates with any correctly sized metric bolt or threaded rod.

• Metric bolts, screws and threaded rod: fits any correctly sized metric bolt, screw or threaded rod.

Installation Guidance

• Match the nut to the corresponding metric bolt, screw or threaded rod diameter and thread pitch shown in the specification table above
• Tighten with a calibrated torque wrench to the fastener manufacturer's recommended setting rather than by feel
• Fit a flat washer under the nut to spread the clamping load over a wider bearing surface
• Where the assembly will be subject to vibration, add a spring or serrated lock washer for extra security against loosening
• Use a standard open-end or socket spanner sized to the width across flats given in the specification table above

Common Questions

Which spanner size do I need?
Match the spanner or socket to the width across flats: an M6 nut takes 10mm, an M8 nut 13mm, an M10 nut 17mm and an M12 nut 19mm. The size for every nut is in the Specification table.

Will the nut fit my bolt?
Yes, when the diameter and thread pitch match: every nut has a standard right-hand metric coarse thread, so an M10 nut fits an M10 bolt, screw or threaded rod.

What finish do the nuts have?
A bright zinc-plated (BZP) finish, giving a bright silver appearance and general-purpose corrosion resistance.

Do I need a washer?
A flat washer under the nut spreads the clamping load over a wider bearing surface. Where the assembly will be subject to vibration, add a spring or serrated lock washer for extra security against loosening.

What pack sizes are available?
Every size comes in packs of 1, 10, 20, 50 or 100 nuts.
