Value Collection R80064048 Hex Head Cap Screw 5/8-18

Product Description

The VALUE COLLECTION R80064048 is a fully threaded hex head cap screw designed for applications requiring corrosion-resistant fastening in demanding environments. Built from Grade 316 stainless steel, this fastener delivers excellent resistance to chlorides, chemicals, and marine exposure. It features a 5/8-18 UNF thread form and measures 1-3/4 inches under the head, left uncoated to preserve the natural properties of the alloy. Plumbers, marine contractors, chemical plant technicians, and industrial maintenance professionals rely on 316 stainless fasteners where 18-8 or carbon steel would corrode prematurely.

This cap screw is suited for use in wet, saltwater, or chemically active environments including marine hardware assemblies, pool and spa equipment, food processing installations, and industrial piping systems. The fine UNF thread pitch provides strong thread engagement and resistance to loosening under vibration, making it a practical choice for precision assemblies or flanged connections where torque retention matters. It is sold individually and compatible with standard 5/8-18 hex nuts and washers.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in chloride and chemical environments
• 5/8-18 UNF fine thread for high torque retention and secure engagement
• Fully threaded shank provides maximum thread engagement along the entire fastener length
• 1-3/4 inch length under head suits a range of standard joint thicknesses
• Uncoated finish maintains base alloy properties without added plating or treatment

Compatibility

Designed as a standard inch-series UNF hex head cap screw compatible with any 5/8-18 threaded hex nut, coupling nut, or tapped hole conforming to UNF thread standards.

Installation Notes

Installation is performed by maintenance technicians, plumbers, or pipefitters using a standard hex wrench or socket sized for a 5/8-inch hex head fastener. Ensure mating threads are clean and free of debris before installation. When used in flanged or pressure-bearing assemblies, follow applicable code requirements such as ASME or ANSI standards for fastener torque and joint integrity. Avoid mixing stainless fasteners with dissimilar metals in submerged or wet environments to minimize galvanic corrosion risk.
