Value Collection 244706 Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 244706 is a 5/16-18 UNC hex socket cap screw manufactured from Grade 316 stainless steel. It features a 1/4-inch hex drive and measures 1.5 inches in length under the head. The socket cap head design allows installation in tight or recessed spaces where a standard wrench cannot reach. Grade 316 stainless steel provides elevated corrosion resistance compared to Grade 304, making this fastener well suited for wet, chemical, or marine environments. Mechanical contractors, pipefitters, electricians, and maintenance technicians use socket cap screws when torque control and a low-profile head are both required.

This fastener is appropriate for general industrial, mechanical, and structural assembly applications where 5/16-18 UNC threading is specified. The 1.5-inch under-head length suits medium-depth through-hole and tapped-hole applications across a range of base materials. Grade 316 stainless is commonly specified in coastal installations, food-service equipment, chemical processing skids, plumbing support hardware, and HVAC component mounting where moisture or corrosive agents are present.

Key Features

• 5/16-18 UNC thread form for compatibility with standard inch-series tapped holes
• 1/4-inch hex socket drive accepts standard Allen keys and hex bit drivers
• 1.5-inch length under head provides versatility across common material thicknesses
• Grade 316 stainless steel construction for superior corrosion and pitting resistance
• Socket cap head profile permits installation in confined or countersunk locations

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any application requiring a 5/16-18 UNC fastener with a 1/4-inch hex drive and 1.5-inch under-head length.

Installation Notes

Install using a 1/4-inch hex key or Allen bit driver rated for the required torque. Ensure the mating tapped hole or nut is clean and free of debris before threading to prevent galling, which is a known risk with stainless steel fasteners. Apply an anti-seize compound when fastening into stainless or aluminum tapped holes to reduce the likelihood of thread seizure. Always verify thread engagement depth meets the requirements of the applicable mechanical or structural specification before torquing to final value.
