Value Collection 208785B Hex Cap Screw 1/2-13x3 18-8 Ss

Product Description

The VALUE COLLECTION 208785B is a hex head cap screw sized 1/2-13 x 3 inches, manufactured from 18-8 stainless steel for reliable corrosion resistance in demanding environments. The fastener features a Unified National Coarse (UNC) thread standard, a 3/4-inch hex drive, and a 3-inch length measured under the head. It is a standard inch-system fastener suited for structural and mechanical assembly work across industrial, commercial, and trade applications. Plumbers, pipefitters, HVAC technicians, and electricians routinely use this screw grade when corrosion resistance and moderate strength are both required.

This cap screw is appropriate for use in wet, outdoor, or chemically exposed environments where carbon steel fasteners would corrode. Typical applications include equipment mounting, pipe flange assembly, bracket installation, and panel fastening in HVAC, plumbing, and electrical systems. The 18-8 stainless grade offers good weldability and formability alongside its corrosion resistance, making it a widely stocked general-purpose fastener for service technicians and contractors working across multiple trade disciplines.

Key Features

• 18-8 stainless steel construction resists rust and corrosion in wet and outdoor environments
• 1/2-13 UNC thread for broad tool and hardware compatibility
• 3-inch length under head provides deep grip for structural connections
• 3/4-inch hex drive works with standard wrenches and sockets
• Inch measurement system — fits standard US fastener specifications

Compatibility

Designed as a general-purpose inch-series hex head cap screw compatible with any 1/2-13 UNC tapped hole or matching hex nut in standard US fastener applications.

Installation Notes

Installation of 1/2-13 hex head cap screws is appropriate for any licensed trade technician performing mechanical or structural assembly. Ensure mating threads are clean and free of debris before installation. Use a calibrated torque wrench appropriate for the joint material and application — do not rely on feel alone when fastening into softer base materials such as aluminum or plastic. Avoid mixing stainless steel fasteners with dissimilar metals in highly conductive or submerged environments without appropriate anti-seize compound to prevent galling.
