Value Collection 014127PR Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 014127PR is a hex socket cap screw designed for secure, torque-resistant fastening in demanding industrial and mechanical applications. It features a 3/8-16 UNC thread size and a 5/8-inch length under head, driven by a 5/16-inch hex key. Manufactured from grade 316 stainless steel with a bright, uncoated finish, this fastener offers strong corrosion resistance, making it well-suited for wet, chemical-exposed, or marine environments. Machinists, maintenance technicians, and industrial mechanics install this type of fastener where reliable clamping force and resistance to loosening under vibration are required.

This screw is used across a wide range of applications including equipment assembly, machine guarding, pump and valve mounting, and general mechanical fabrication. The 3/8-16 UNC coarse thread pattern is one of the most common inch-series thread standards, allowing compatibility with a broad inventory of nuts, inserts, and threaded holes found in industrial machinery and structural components. It is appropriate for both light commercial and heavy industrial settings where stainless steel is specified for environmental or sanitary reasons.

Key Features

• Grade 316 stainless steel construction provides superior corrosion and chemical resistance
• 3/8-16 UNC coarse thread for broad compatibility with standard inch-series threaded components
• 5/16-inch internal hex drive allows high torque application with a standard Allen key or hex bit
• 5/8-inch length under head suits shallow-to-medium clamping depth requirements
• Bright, uncoated finish maintains dimensional accuracy and thread fit without coating buildup

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw suitable for threaded holes, hex nuts, and inserts machined or tapped to ANSI inch-series coarse thread specifications.

Installation Notes

Installation is performed with a 5/16-inch hex key or Allen-head driver bit. Ensure the mating threaded hole or nut meets 3/8-16 UNC specifications before installation to avoid cross-threading. Applying appropriate thread lubricant or anti-seize compound is recommended when fastening 316 stainless steel into stainless or similar material to reduce the risk of galling. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.
