Nuts Assortment Kit

The Nuts kit holds hex full nuts, nyloc nuts and washers across the matching size range for the Bolts kit - the natural pair for general assembly work.

WHAT IS IN THE KIT

Typical 18-piece nut kits hold M4 to M12 hex nuts in zinc plated finish, sometimes with matching nyloc nuts and flat washers in a separate compartment.

WHEN TO PICK THIS KIT

Pick a Nuts kit when assembling bolted joints where the through-thickness is unknown until the job starts, or when servicing equipment that uses many different bolt sizes.

RESTOCKING SINGLE SIZES

When the M8 nyloc runs out faster than the others, top up loose nyloc nuts from our Nuts range, where single sizes are stocked in bulk packs from 25 to 1000+ pieces.

FREQUENTLY ASKED QUESTIONS

What sizes are in a Nuts Assortment Kit?

Typical 18-piece nut kits hold M4 to M12 hex nuts in zinc plated finish, sometimes with matching nyloc nuts and flat washers in a separate compartment. Check the kit description on the specific product page for the exact piece count and size list - different kits in this category cover different size breadth at different piece counts.

What finish and class are the Nuts in the kit?

Most Nuts kits ship with the standard general-assembly finish and class noted in the kit description. For outdoor, wet or coastal use, look for the stainless variant where available. For structural and load-rated work, confirm the Class rating on the kit before installing. The full finish and class options for the individual items are listed on the Nuts range page.

Can I buy single sizes from a Nuts kit?

Yes. Every kit cross-references the matching main category for loose-stock purchase of single sizes. When one size depletes ahead of the others, restock from our Nuts range where individual sizes are stocked in bulk packs from 25 to 1000+ pieces.

What types of nuts are in a Nuts Assortment Kit?

Most Nuts kits ship a mix of hex full nuts and matching nyloc (nylon-insert) nuts. Some 50+ piece kits also include flat washers and spring washers in separate compartments. Specialty nuts (wing nuts, dome nuts, cage nuts, security nuts) are sold separately - see the Nuts main category for the full range.

Does the Nuts kit match the Bolts kit sizes?

Yes - the Nuts kit covers the matching size range to the standard Bolts kit (M4 to M12 metric typically). Pairing the two kits gives complete bolted-joint coverage without leftover odd sizes.

What jobs is the Nuts Assortment Kit best for?

Pick a Nuts kit when assembling bolted joints where the through-thickness is unknown until the job starts, or when servicing equipment that uses many different bolt sizes.

How do I identify which size in the kit I need?

Match the nut against the compartment labels on the kit case. Nuts are sized by thread diameter and pitch, and measured across the flats (AF) of the hex for spanner size. See the identify your nut size guide for the full method.
