Fastener & Product FAQs

Quick answers on standards, samples, tolerances, and custom quoting.

Which fastener standards do you produce to?↓
We produce to DIN, ISO, ANSI/ASME, GB, and JIS standards, and we build to custom drawings (build-to-print) for non-standard parts.
Can you match a sample part I send?↓
Yes. Send us the physical sample or photos with measurements, and we will reverse-engineer the part, recommend material and finish, and produce matching pieces.
Do you offer heat treatment and surface finishing?↓
Yes. We provide heat treatment for strength grades up to 12.9, plus zinc plating, hot-dip galvanizing, Dacromet, black oxide, nickel plating, and passivation — all with our in-house or certified partner processes.
What tolerances can you hold?↓
CNC-machined features are held to +/- 0.01 mm; stamped and cold-headed features typically +/- 0.05 mm. Tighter tolerances are possible for critical dimensions — confirm on your drawing.
How do I get a quote for custom fasteners?↓
Send your drawing (PDF, DXF, or 3D) and target quantity to [email protected] or use the contact form. We reply within 24 hours with pricing, tooling cost, sample lead time, and production schedule.
Do you provide inspection reports with shipments?↓
Yes. Every shipment can include material certificates and inspection reports covering dimensions, hardness, tensile strength, and salt-spray results, per your quality agreement.
