Alloy Steel Fastener Body With Square Collared Nut and Central Through-Hole

For production of each square collared nut, we hold your tolerance specifications as the primary control point. We run jobs from your approved drawing with clear revision control to keep inspections aligned over time and across batches. Quotes reflect material choice and surface work. Lead times are set by batch size and agreed inspection scope so you can plan production confidently. From our IATF 16949 line, we produce square collared nut to keep fit consistent across repeat runs. In Suzhou, our IATF 16949-certified factory manages precision metal fastening production for these runs. Note the target quantity and delivery timing to confirm lead time and cost.
