Value Collection R88412828 Hex Cap Screw 5/16-24 Grade 316

Product Description

The VALUE COLLECTION R88412828 is a hex head cap screw sized 5/16-24 x 1-1/2 inches, manufactured from Grade 316 stainless steel with no surface coating applied. It uses a Unified Fine (UNF) thread standard and features partial threading along the shank. The screw measures its 1-1/2 inch dimension as length under head. At approximately 0.0097 pounds per piece, it is a compact fastener suited to precision assembly work. Licensed trades and maintenance professionals use this type of fastener when corrosion resistance and thread accuracy are required in demanding environments.

This cap screw is appropriate for use in plumbing, HVAC, electrical enclosure assembly, pool equipment mounting, and marine or chemical-exposure environments where Grade 316 stainless steel is specified for superior chloride and corrosion resistance. The fine 5/16-24 UNF thread pitch provides greater thread engagement per inch compared to coarse thread, making it well suited to applications that require precise clamping force or resistance to vibration loosening. It is sold in a minimum order quantity of 10 pieces.

Key Features

• Grade 316 stainless steel construction for high corrosion and chloride resistance
• 5/16-24 UNF fine thread for increased thread engagement and vibration resistance
• Partially threaded shank for controlled clamping and shoulder alignment
• Uncoated finish — no galvanic incompatibility risk from plating in stainless assemblies
• Length under head: 1-1/2 inches for consistent dimensional reference during installation

Compatibility

Designed as a standard UNF hex head cap screw for use in any application calling for a 5/16-24 partially threaded fastener in Grade 316 stainless steel.

Installation Notes

Installation is performed with a standard hex wrench or socket driver sized for a 5/16-24 hex cap screw head. Confirm mating thread is tapped to UNF specification before installation to avoid cross-threading. In stainless-to-stainless assemblies, apply an appropriate anti-seize compound to prevent galling during torquing. Always de-energize or depressurize any equipment before accessing fastened components.
