Stainless Bolt Industries focuses in offering quality SS 304 Allen Cap screws that are made for uses requiring strength, accuracy, and resistance to corrosion. These fasteners, also referred to as socket head cap screws, have a cylindrical head with an internal hex drive that makes it simple to install them with an Allen key. They are perfect for use in industrial machinery, marine, automotive, and structural applications because of their outstanding resistance to rust, chemicals, and high temperatures. They are made from stainless steel 304 (A2 Grade). Our SS 304 Allen Cap screws guarantee safe fastening and long-lasting performance, even in the most demanding conditions, thanks to their excellent mechanical qualities and clean, professional finish.
The SS 304 Allen Cap is a high-strength fastener with a cylindrical head and internal hexagonal drive, designed for use with Allen (hex) keys. Manufactured from Stainless Steel 304 (A2 Grade), this cap screw offers excellent corrosion resistance, making it suitable for both indoor and outdoor environments, including marine, chemical, and industrial applications. The SS 304 material provides a strong balance of mechanical strength and corrosion protection, while its non-magnetic and heat-resistant properties enhance its versatility in critical engineering assemblies. Commonly used in machine parts, die fixtures, automotive components, and structural assemblies, SS 304 Allen Caps ensure reliable performance and a neat, flush finish in tight or precision-driven spaces.
