Value Collection -30604-2 Hex Head Cap Screw 5/8-11

Product Description

The VALUE COLLECTION -30604-2 is a 5/8-11 UNC hex head cap screw with a 1-1/4-inch length under head, manufactured from Grade 316 stainless steel. This fastener is built for applications where corrosion resistance is critical. The 15/16-inch hex drive allows standard socket or wrench engagement. Grade 316 stainless steel provides superior resistance to chlorides, acids, and marine environments compared to Grade 304, making it a reliable choice for demanding service conditions. Plumbers, pipefitters, HVAC technicians, and industrial maintenance trades commonly specify this grade when fastening flanges, brackets, or equipment in wet or corrosive environments.

This cap screw suits residential and commercial applications where exposure to moisture, chemicals, or saltwater is a factor. Typical installation scenarios include pipe flange connections, equipment mounting in mechanical rooms, pool equipment enclosures, and outdoor or coastal installations. The UNC thread form is compatible with standard inch-series tapped holes and nuts. This fastener is sold individually, with a minimum order quantity of 25 pieces.

Installation Notes

Installation is performed by licensed tradespeople or qualified maintenance personnel using a standard 15/16-inch socket or open-end wrench. De-energize or shut down all associated equipment before fastener service. When used in pressure-rated assemblies, refer to applicable code requirements such as ASME or ANSI standards for proper torque and joint specifications. Avoid mixing stainless steel fasteners with dissimilar metals in submerged applications to minimize galvanic corrosion risk.
