Value Collection R32016026 Hex Cap Screw 1/2-13 X 8 in 316 Ss

Product Description

The VALUE COLLECTION R32016026 is a partially threaded hex head cap screw designed for heavy-duty fastening applications where corrosion resistance is critical. Sized at 1/2-13 UNC thread with an 8-inch length under head, this fastener is manufactured from Grade 316 stainless steel and supplied with an uncoated finish. The 316 alloy offers superior resistance to chlorides and marine environments compared to 304-series stainless, making it a preferred choice for plumbing, HVAC, and industrial installations exposed to moisture or chemical exposure. Licensed tradespeople and maintenance professionals install these in structural and mechanical assemblies requiring reliable clamp load and long-term corrosion resistance.

This cap screw is suited for residential and commercial applications where stainless steel fasteners are specified by code or engineering requirement. Typical use cases include pipe flange connections, equipment mounting, pump and blower assemblies, pool and waterpark equipment, and coastal or chemical-plant installations. The partially threaded shank provides a smooth bearing surface in the grip area, which is important when fastening through clearance holes in metal or composite materials. Sold individually with a minimum order quantity of 5 pieces.

Key Features

• Grade 316 stainless steel construction for enhanced chloride and corrosion resistance
• 1/2-13 UNC thread standard for broad tool and nut compatibility
• 8-inch length under head accommodates deep grip or multi-layer assemblies
• Partially threaded shank provides a clean bearing surface through the grip zone
• Uncoated finish maintains full dimensional tolerances for precision fit
• Hex drive head compatible with standard 3/4-inch hex wrench and socket tooling

Compatibility

Designed as a standard 1/2-13 UNC hex head cap screw compatible with any application specifying a 1/2-13 inch-series nut, tapped hole, or flanged connection using unified coarse thread fasteners.

Installation Notes

Installation should be performed by a qualified mechanic, pipefitter, or maintenance technician following applicable mechanical and plumbing codes. Ensure mating threads and seating surfaces are clean and free of debris before assembly. Use a calibrated torque wrench when specified torque values are called out in equipment documentation. Never mix stainless steel fasteners with dissimilar metals in submerged or highly conductive environments without considering galvanic compatibility.
