๐ง What Is a Cap Head Screw & What Is a Capscrew? โ Technical Deep Dive
A cap head screw (also called a capscrew or socket head cap screw) is a threaded fastener with a cylindrical head and a hexagonal drive socket. It delivers high clamping force in tight spaces where a wrench cannot reach. Used extensively in automotive, machinery, construction, and aerospace assemblies.

โ Frequently Asked Questions About Cap Head Screws & Capscrews
โ What is the difference between a cap head screw and a capscrew?
Technically, they are the same. โCap head screwโ describes the shape (cylindrical head), while โcapscrewโ is a broader term for a fastener that is threaded into a tapped hole. Both refer to socket head cap screws (SHCS) in most industrial contexts.
โ What grade of cap head screw should I use for high-stress applications?
For automotive and machinery, grade 12.9 (alloy steel) offers the highest tensile strength (1,220 MPa). For corrosive environments, choose 316 stainless steel. We help you select the optimal grade based on your load and environment.
โ Do you offer custom lengths and thread patterns?
Yes. We provide OEM/ODM customization for cap head screws, including non-standard lengths, fine/coarse threads, partial threads, and custom head markings. Minimum order quantity: 2,000 pcs for custom specs.
โ What is your typical lead time for wholesale orders?
Standard lead time is 15โ25 working days after confirmation. For urgent orders, we offer an express service (10โ15 days) at a small premium. We ship via sea, air, or express courier (DHL, FedEx, UPS).
โ How do you ensure quality control?
Every batch undergoes dimensional inspection, hardness testing, tensile strength testing, and surface finish check per ISO 898-1 and DIN 912 standards. We provide mill test certificates with each shipment.
โ What payment terms do you accept?
We accept T/T (wire transfer), L/C, PayPal, and Alibaba Trade Assurance. For long-term partnerships, we can negotiate net 30/60 terms (subject to credit approval).
โ Do you offer free samples?
