Value Collection 399182PS Hex Cap Screw 1/2-13 X 3-1/2 316 Ss

Product Description

The VALUE COLLECTION 399182PS is a fully threaded hex head cap screw designed for fastening applications that demand corrosion resistance and dimensional accuracy. Sized at 1/2-13 x 3-1/2 inches (length under head), it uses a Unified National Coarse (UNC) thread form and is manufactured from Grade 316 stainless steel with a bright, uncoated finish. The fully threaded shank provides consistent thread engagement along the entire clamping length, making it well suited for through-bolt installations or applications where nut positioning must be adjustable. Licensed tradespeople and maintenance technicians working in corrosive or wet environments rely on Grade 316 material for its enhanced resistance to chlorides and chemical exposure compared to standard 304 stainless.

This cap screw is appropriate for use in commercial and industrial environments where exposure to moisture, salt air, mild chemicals, or outdoor conditions is expected. Typical applications include equipment mounting, pipe support assemblies, structural bracketing, and general mechanical fastening in HVAC, plumbing, pool, and marine-adjacent service environments. The 3/4-inch hex drive size accommodates standard combination wrenches and sockets commonly found in every trade toolkit. Minimum order quantity is 5 pieces; each package contains 1 piece.

Key Features

• Grade 316 stainless steel construction for superior corrosion and chloride resistance
• Fully threaded shank from head to tip for maximum thread engagement flexibility
• UNC 1/2-13 thread form for broad compatibility with standard nuts and tapped holes
• Bright, uncoated finish — no plating or coating to degrade in harsh environments
• 3/4-inch hex drive size fits standard open-end, box, and socket wrenches
• 3-1/2-inch length under head measured per standard length-under-head convention

Compatibility

Designed for use with standard 1/2-13 UNC hex nuts, flat washers, and lock washers in inch-measurement fastener assemblies. Suitable for tapped holes and clearance-hole applications calling for 1/2-13 UNC fully threaded hex cap screws in Grade 316 stainless steel.

Installation Notes

Installation should be performed by a qualified mechanic or licensed tradesperson following the applicable assembly specifications for the equipment or structure being fastened. Shut down and de-energize any equipment before fastening work begins. Use a properly sized 3/4-inch wrench or socket to avoid rounding the hex head. When installing stainless steel fasteners, apply an anti-seize compound to the threads to prevent galling, which is common with austenitic stainless alloys under torque.
