Frequently asked questions
Are DIN 934 and ISO 4032 hex nuts the same part?
Both designations cover hex nuts and both are in the quoted range; the standards differ in dimensional details between editions, so the order should carry the designation your drawing uses. Nylon insert lock nuts are covered separately (DIN 985 / ISO 10511) — name the lock type explicitly if the joint needs one.
Which nut grade matches a class 8.8 bolt?
Nuts are matched to the bolt property class — the quoted range covers ISO 898-2 nut classes (8 / 10 / 12) and A2 / A4 stainless to ISO 3506-2, so a class 8 nut is quoted against a class 8.8 bolt assembly. Match the pairing your joint design specifies and confirm it on the RFQ; substituting a different class pairing is an engineering decision, not a price decision.
What is the MOQ and lead time for nuts?
The minimum order quantity is 10,000 pieces. Stock items ship in 3–7 days. Size range runs to M36 / 1-1/2", with metric and inch threads (M, UNC/UNF, BSW/BSF); non-stock sizes are confirmed at quotation.
