What decides the price

In order of impact
Nut class versus bolt class

A class 8 nut on a 10.9 bolt moves the weak point to the nut. Matching the pair is the whole point.

Locking method

A nylon insert nut is single-use in practice. An all-metal nut survives heat and re-use where nylon would creep.

Bearing surface

A flange nut spreads load without a washer. On thin sheet, that difference decides whether the panel deforms.

Worth checking before you order

Buying nuts by diameter only

Diameter, pitch and class all have to match the bolt. Two of three is a joint that fails inspection.

Re-using nylon lock nuts

The insert deforms on first use. Second use loses most of the prevailing torque.

Questions

Do you supply nuts matched to your bolts?+

Yes, and we quote them as a pair so the classes match. Buying them separately is how mismatches happen.

Are all-metal lock nuts available in 10.9?+

The nut class is 10 where the bolt is 10.9. Tell us the joint and we confirm the pairing.

Send the specification, not the product name.

Grade, size, thread standard and coating are what a quote is built from. A product name alone produces a price that changes twice before the order.
