Value Collection 015199PR Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 015199PR is a 5/16-18 UNC hex socket cap screw designed for secure fastening in mechanical, structural, and industrial assemblies. It features a 1/4 inch hex drive and a 3/4 inch length under head with full threading along the shank. Manufactured from alloy steel and finished with a black oxide coating, it provides moderate corrosion resistance and a low-reflectance surface. This screw meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it a reliable choice for high-strength bolted connections where socket drive access is required.

This cap screw is suited for use in general manufacturing, machinery maintenance, and equipment fabrication applications. The 5/16-18 UNC coarse thread pattern is a common specification in both OEM and MRO environments. Fully threaded construction maximizes thread engagement across the full length of the fastener, which is particularly useful in thinner material joints or when thread engagement depth is limited. Licensed mechanics, millwrights, and maintenance technicians typically install this type of fastener using a 1/4 inch hex key or socket driver.

Key Features

• 5/16-18 UNC coarse thread for broad compatibility in standard inch-dimensioned assemblies
• Fully threaded shank maximizes thread engagement in shallow blind holes
• Alloy steel construction for high tensile strength under load
• Black oxide finish provides mild corrosion resistance and reduces surface glare
• 1/4 inch hex socket drive for use with standard Allen keys or hex bit drivers
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw for use in any application requiring ASME/ANSI B18.3-compliant inch-series socket fasteners.

Installation Notes

Install using a 1/4 inch hex key or socket bit driver. Ensure mating threads are clean and free of debris before installation. Do not over-drive; stop when the head is fully seated against the mating surface. Follow applicable torque specifications from engineering drawings or recognized fastener reference standards for ASTM A574 alloy steel cap screws.
