Value Collection 209016 Hex Head Cap Screw 5/8-11 X 4.5in Ss

Product Description

The VALUE COLLECTION 209016 is a hex head cap screw designed for general fastening applications requiring corrosion-resistant hardware. The fastener measures 5/8-11 thread size with a 4-1/2 inch length under the head and conforms to Unified National Coarse (UNC) thread standards. Constructed from 18-8 stainless steel, it offers reliable resistance to rust and oxidation in wet or chemically active environments. The 15/16 inch hex drive is compatible with standard wrenches and sockets. This screw is suited for mechanical assemblies, structural connections, and equipment installations where stainless hardware is specified.

This fastener is commonly used in HVAC equipment mounting, plumbing system supports, pool and water treatment equipment, and general industrial or commercial mechanical assemblies. It is appropriate for both indoor and outdoor installations where stainless steel is called out by specification. Tradespeople in HVAC, plumbing, electrical, and pool service regularly stock stainless cap screws of this size for corrosion-prone environments and equipment installations requiring long-term fastener integrity.

Installation Notes

Installation is performed with a 15/16 inch wrench or socket driver. Always ensure the mating threaded component matches the 5/8-11 UNC thread specification before installation. De-energize and depressurize any equipment before fastening or removing hardware in live systems. Apply anti-seize compound when joining stainless fasteners to stainless or aluminum threads to prevent galling.
