Value Collection 500188PS Hex Head Cap Screw 1/2-13 X 4.5in

Product Description

The VALUE COLLECTION 500188PS is a fully threaded hex head cap screw designed for general-purpose fastening in mechanical, structural, and trade applications. It features a 1/2-13 UNC thread pattern and measures 4-1/2 inches under the head. Constructed from Grade 2 steel with a zinc-plated finish, it provides adequate corrosion resistance for light to moderate environmental exposure. The fully threaded shank allows engagement along the entire fastener length, making it well suited for through-bolt and nut-and-bolt assemblies. Licensed trades including HVAC technicians, plumbers, and electricians commonly use fasteners of this type when securing equipment, mounting brackets, and panel frames.

This hex head cap screw is appropriate for residential and commercial applications where a standard UNC-thread steel fastener is specified. Typical uses include securing mechanical equipment bases, electrical enclosures, structural framing members, and piping supports. The 3/4-inch hex drive size is compatible with standard sockets and wrenches found in most trade toolkits. The zinc-plated finish makes it suitable for interior and semi-protected outdoor installations where mild corrosion resistance is sufficient.
