High Strength Full Thread/Half Thread Blue-White Zinc Plated Carbon Steel Stainless Steel Hex Head Bolts
High Strength Full Thread / Half Thread Blue-White Zinc Plated Carbon Steel Hex Bolts
A bolt is a type of threaded fastener with an external male thread. It is often confused with a screw, but bolts are typically used with nuts and require a wrench for installation. A hex cap screw, on the other hand, has a hexagonal head and is designed to be driven by a wrench or socket.
ASME B18.2.1 compliant cap screws have tighter tolerances than standard hex bolts, particularly in terms of head height and shank length. This means that while a hex cap screw will always fit where a hex bolt is used, the reverse may not always be true.
These high-strength hex bolts are available in full or half thread versions and are made from carbon steel, offering excellent durability and strength. They feature a blue-white zinc plating finish, which provides corrosion resistance and a clean, professional appearance.
They are suitable for use in machinery, construction, and various industrial applications. The bolts meet international standards such as DIN, ANSI, GB, JIS, BSW, and GOST, ensuring compatibility across different markets and industries.
