How to Choose the Right Screw
Start with the mating material: sheet metal and plastics call for self-tapping or self-drilling screws, while machined assemblies typically use machine screws with pre-tapped holes. Next, define the drive type and head style for the tooling you use on the production line, then confirm the corrosion resistance you need — from plain carbon steel for indoor use to A4 stainless or Dacromet for outdoor and marine environments. Send us your drawing or application details and our engineers will confirm the exact standard, material grade and finish.
Frequently Asked Questions
What standards do your screw manufacturers work to?
Our certified factories produce to ISO, DIN, ASTM and GB standards. Most metric sizes are interchangeable across these systems — send your drawing and we will confirm the equivalent standard.
What should I include in my screw RFQ?
Include the standard, nominal size, length, drive and head type, material grade, surface treatment, quantity and target price. For custom parts, add 3D or 2D drawings.
Can I order small quantities first?
Yes. Samples are typically ready in 1–3 days and small batch production in 10–15 days, so you can validate quality before mass production.
Do you offer OEM screws?
Yes, custom heads, threads, materials and finishes are available through our OEM/ODM network, with FAI and full inspection documentation on request.
