Value Collection 202778C Hex Head Cap Screw 1/2-13 X 1.5 in 316 Ss

Product Description

The VALUE COLLECTION 202778C is a 1/2-13 x 1-1/2 inch hex head cap screw manufactured from Grade 316 stainless steel. It features a Unified National Coarse (UNC) thread standard and a 3/4 inch hex drive. Grade 316 stainless steel provides strong resistance to corrosion and chemical exposure, making this fastener well suited for demanding environments including marine, chemical processing, and outdoor industrial applications. Licensed tradespeople, maintenance technicians, and mechanical contractors install this type of fastener across a wide range of structural and equipment-mounting tasks.

This hex head cap screw is used wherever a corrosion-resistant threaded fastener is required. Common applications include HVAC equipment mounting, plumbing fixture attachment, pool and spa equipment installation, and general mechanical assembly in wet or chemically aggressive environments. The 1/2-13 UNC thread size is a widely used coarse-thread standard appropriate for general-purpose fastening in metal, through-hole, and threaded insert applications. Residential and commercial service technicians frequently specify Grade 316 stainless hardware for coastal and outdoor installations.

Key Features

• Grade 316 stainless steel construction for superior corrosion and chemical resistance
• 1/2-13 UNC coarse thread for broad compatibility with standard threaded hardware
• 1-1/2 inch length under head for typical medium-depth fastening applications
• 3/4 inch hex drive for use with standard wrenches and sockets
• Inch measurement system for compatibility with standard US fastener tooling

Compatibility

Designed as a standard 1/2-13 UNC hex head cap screw for use in applications requiring Grade 316 stainless steel fasteners across HVAC, plumbing, pool, and general mechanical assemblies.

Installation Notes

Installation should be performed by a qualified technician or mechanic using a properly sized 3/4 inch wrench or socket. Always de-energize and lock out equipment before fastening or removing hardware on mechanical or electrical assemblies. Apply an anti-seize compound compatible with stainless steel to prevent galling, which is common with stainless fasteners under torque. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener torque and assembly sequence.
