Not sure what size or thread you have or need?
Two ways to confirm before you order - whichever you already know about your fastener.
1If you know the fastener diameter

Compare your fastener to our visual size guide to confirm size, pitch and length.

2If you have the spanner or socket

Match your spanner / socket AF (across-flats) to the size it fits - our reference chart covers every metric and imperial size we stock.

Bolts Assortment Kit

The Bolts kit holds a curated mix of hex head bolts across the most-used metric and imperial sizes - the on-truck or on-bench answer to 'do you have an M8 by 30?' without having to drive back to the store.

WHAT IS IN THE KIT

Typical 30 to 84-piece bolt kits cover M4 to M12 metric, 1/4 to 1/2 inch imperial, lengths 10 to 60mm. Mixed Class 4.6 and 8.8 in zinc plated finish unless the kit description states otherwise.

WHEN TO PICK THIS KIT

Pick a Bolts kit when the job involves general assembly across a range of sizes - flat-pack assembly, machinery rebuilds, automotive bench work. For structural connections check the Class on the kit before buying.

RESTOCKING SINGLE SIZES

When you use up one bolt size faster than the others (the M8 x 30 is always the first to go), reorder that size loose from our Bolts range, where single sizes are stocked in bulk packs from 25 to 1000+ pieces.

FREQUENTLY ASKED QUESTIONS

What sizes are in a Bolts Assortment Kit?

Typical 30 to 84-piece bolt kits cover M4 to M12 metric, 1/4 to 1/2 inch imperial, lengths 10 to 60mm. Mixed Class 4.6 and 8.8 in zinc plated finish unless the kit description states otherwise. 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 Bolts in the kit?

Most Bolts 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 Bolts range page.

Can I buy single sizes from a Bolts 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 Bolts range where individual sizes are stocked in bulk packs from 25 to 1000+ pieces.

Are nuts and washers included with the Bolts kit?

Some Bolts kits ship as bolts only; others ship as bolt + matching nut + matching washer in a single compartmented case. Check the kit description for 'with matching nuts' or similar wording. For a separate Nuts kit, see the Nuts sub-category above.

What is the difference between Class 4.6 and 8.8 bolts in a kit?

Class 4.6 is mild-steel general-purpose - fine for non-structural assembly, gates, brackets and shed work. Class 8.8 is medium-carbon alloy heat-treated, with roughly 2x the tensile strength - the right choice for machinery, suspension, structural connections and anywhere shear load matters. Check the kit description for the Class rating before installing in a load-rated joint.

What jobs is the Bolts Assortment Kit best for?

Pick a Bolts kit when the job involves general assembly across a range of sizes - flat-pack assembly, machinery rebuilds, automotive bench work. For structural connections check the Class on the kit before buying.

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

Match the application part against the compartment labels on the kit case. For bolts and screws, measure the diameter at the thread (not the head) and the length under the head. For nuts, measure across the flats (AF) of the hex. See the identify your bolt or screw size walk-through for the full method.

Yes. The Bolts kit range is stocked in our Brisbane warehouse and ships same business day on orders placed before 1pm AEST. 98.75% of orders ship same day from over 25,000 stock lines.
