--- **ANSI/BS Hex Socket Cap Bolt with Gasket & Spring Washer** A bolt is a type of threaded fastener with an external male thread and is often confused with a screw. A hex cap screw has a hexagonal head and is typically driven by a wrench or spanner. An ASME B18.2.1 compliant cap screw has tighter tolerances for the head height and shank length compared to a standard hex bolt, ensuring a more precise fit. --- ### **Product Details** | **Product Name** | **ANSI/BS Hex Socket Cap Bolt with Gasket & Spring Washer** | |------------------|-------------------------------------------------------------| | **Standard** | DIN, ASTM/ANSI, JIS, EN ISO, AS, GB | | **Material** | Stainless Steel: SS201, SS303, SS304, SS316, SS316L, SS904L, F593 | | | Steel Grade: DIN 4.6, 4.8, 5.6, 5.8, 8.8, 10.9, 12.9; SAE Gr. 2, 5, 8; ASTM 307A, 307B, A325, A394, A490, A449 | | **Finishing** | Zinc (Yellow, White, Blue, Black), Hot-Dip Galvanized (HDG), Black Oxide, Geomet, Dacromet, Anodization, Nickel Plated, Zinc-Nickel Plated | | **Production Process** | M2-M24: Cold Forging; M24-M100: Hot Forging; CNC Machining for Custom Parts | | **Customized Lead Time** | Busy Season: 15–30 Days; Slack Season: 10–15 Days | | **Stock Products** | Steel: 4.8, 8.8, 10.9 Grades (DIN 6923, GB5783, GB5782); Stainless Steel: All DIN Standard Bolts | | **Free Samples** | Available for standard fasteners | | **Contact Us** | Visit [www.hainafastener.com](http://www.hainafastener.com) for more details | --- ### **Why Choose Us?** - **Professional Manufacturer**: We design and produce all fasteners according to your specifications and performance requirements. - **Quality Guaranteed**: Our products undergo durability testing and advanced technical design to ensure long-lasting performance. - **Cost-Effective**: Competitive pricing with direct factory supply. - **Comprehensive Solutions**: With over 20 years of experience, we provide a wide range of fastener options to meet your needs. - **Customized Services**: We offer tailored solutions based on your samples or drawings. - **Expert Support**: If you're unsure about which product you need, feel free to contact us anytime for professional assistance.
