Value Collection 208748 Hex Head Cap Screw 18-8 Ss Unc

Product Description

The VALUE COLLECTION 208748 is a hex head cap screw designed for heavy-duty fastening applications in industrial, mechanical, and structural assemblies. Manufactured from 18-8 stainless steel, this fastener delivers solid corrosion resistance in wet, outdoor, and mildly chemical environments. The screw features a 1-8 thread size with a Unified National Coarse (UNC) thread standard and measures 4-1/2 inches under the head. The hex drive head accepts standard wrenches and sockets, making installation and removal straightforward for trade professionals and maintenance technicians.

This cap screw is suited for general-purpose fastening where corrosion resistance is required. Common applications include HVAC equipment mounting, plumbing fixture assembly, electrical enclosure hardware, pool equipment installations, and light structural connections. The 18-8 stainless steel grade is widely used in environments exposed to moisture and mild corrosives, making it a practical choice for both indoor and outdoor mechanical assemblies in residential and commercial settings.

Installation Notes

Installation is typically performed by maintenance technicians, millwrights, or trade professionals using an appropriate open-end, box-end, or socket wrench sized for the hex head. Ensure the mating thread is clean and free of debris before installation. Do not overtighten stainless steel fasteners, as galling can occur; applying an anti-seize compound to the threads is a common preventive measure. Always follow applicable mechanical and structural codes for the specific assembly.
