Value Collection MP30583 Hex Head Cap Screw 5/16-18 1in 316 Ss

Product Description

The VALUE COLLECTION MP30583 is a 5/16-18 x 1 inch hex head cap screw machined from Grade 316 stainless steel. It features a Unified National Coarse (UNC) thread form with a 1/2 inch hex drive and a 1 inch length measured under the head. Grade 316 stainless steel provides elevated corrosion resistance compared to Grade 304, making this fastener well suited for wet, chemical, or marine service environments. Maintenance technicians, pipefitters, millwrights, and general contractors install these fasteners where corrosion resistance and reliable clamping force are required.

This hex head cap screw is used in a wide range of industrial, mechanical, and construction applications. Common install scenarios include equipment mounting, structural assemblies, pipe support hardware, pump and valve service, and panel or enclosure fastening. The inch-series thread pattern and standard hex drive make it compatible with common hand tools and power drivers in both shop and field settings. It is appropriate for light to medium clamping loads in corrosive or outdoor environments.

Key Features

• Grade 316 stainless steel construction for superior corrosion and chemical resistance
• 5/16-18 UNC thread for broad tool and hardware compatibility
• 1 inch length under head for consistent clamping depth
• 1/2 inch hex drive accepts standard wrenches and sockets
• Inch measurement system for compatibility with standard US fastener hardware

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 5/16-18 UNC threaded fastener in Grade 316 stainless steel.

Installation Notes

Installation is performed with a standard 1/2 inch open-end, box, or socket wrench. Always ensure mating threads are clean and free of debris before driving. In stainless steel fastener applications, apply an anti-seize compound to prevent galling during installation. Power down or de-energize any equipment being serviced before fastener work begins.
