Value Collection R88412364 Hex Head Cap Screw 5/16-18

Product Description

The VALUE COLLECTION R88412364 is a 5/16-18 UNC hex head cap screw measuring 2-1/4 inches under the head, manufactured from Grade 316 stainless steel with no applied finish coating. Grade 316 stainless provides enhanced corrosion resistance compared to Grade 304, making it a reliable choice for wet, chemical-exposed, or marine environments. The screw features partial threading along the shank, which allows it to bear shear loads and align mating components more effectively than a fully threaded fastener. Sold individually with a minimum order quantity of 10 units, this fastener is suited for maintenance, fabrication, and assembly applications across multiple trades.

This hex head cap screw is commonly used in plumbing, HVAC equipment mounting, pool and spa equipment installations, and general industrial or marine fabrication where stainless fasteners are required. The 5/16-18 UNC thread is a widely specified size for structural and mechanical connections on equipment panels, pipe supports, enclosures, and brackets. The partially threaded shank is appropriate for applications requiring a smooth bearing surface between joined components.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in wet and chemical environments
• 5/16-18 UNC thread form for broad compatibility with standard inch-series tapped holes and nuts
• 2-1/4 inch length under head accommodates moderate material stack-up
• Partially threaded shank provides shear strength and component alignment
• Uncoated finish preserves the natural corrosion resistance of 316 stainless without added treatment

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 5/16-18 UNC tapped hole, nut, or threaded insert in equipment, structures, or assemblies that require Grade 316 stainless steel fasteners.

Installation Notes

Install using a standard hex wrench, socket, or open-end wrench sized for a 5/16-inch hex head cap screw. De-energize and isolate any equipment before fastener service work on electrical or mechanical enclosures. Avoid mixing stainless steel fasteners with dissimilar metals in submerged or high-humidity applications to minimize galvanic corrosion risk. Fastener torque should be determined by the equipment manufacturer specifications or applicable mechanical codes for the assembly.
