Value Collection R57001072 Hex Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION R57001072 is a hex socket cap screw designed for general industrial and mechanical fastening applications. Threaded to 1/2-13 UNC specifications, it features a 3/8-inch internal hex drive and measures 2.75 inches in length under the head. Constructed from 18-8 stainless steel with a bright, uncoated finish, this fastener resists corrosion and maintains strength in wet or mildly corrosive environments. It is suited for assembly work requiring a flush or recessed fastener head driven with a hex key or Allen driver. Machinists, maintenance technicians, and mechanical contractors commonly install this type of fastener in equipment frames, fixtures, and structural assemblies.

This cap screw is appropriate for both light industrial and commercial mechanical applications where 1/2-13 UNC threading is specified. The 18-8 stainless steel construction makes it suitable for installations exposed to moisture, mild chemicals, or outdoor conditions. It is commonly used in equipment fabrication, machine guarding, pump housings, and general structural assemblies where a clean, recessed drive is preferred over an external hex head. The uncoated bright finish is compatible with a wide range of mating materials.

Key Features

• 1/2-13 UNC thread size for broad compatibility with standard tapped holes and nuts

• 3/8-inch hex socket drive accepts standard Allen keys and hex bit drivers
• 18-8 stainless steel construction offers corrosion resistance in wet and mildly corrosive environments
• Bright uncoated finish maintains dimensional accuracy without added coating thickness
• UNSPSC code 31161501 for procurement and catalog classification

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw for use in any application with a matching 1/2-13 tapped hole or nut, conforming to standard inch-series fastener specifications.

Installation Notes

Installation requires a 3/8-inch hex key or compatible bit driver. Ensure the mating tapped hole or nut is clean and free of debris before threading. Apply appropriate thread lubricant or anti-seize compound when installing into dissimilar metals to prevent galling of the stainless steel threads. Follow applicable equipment manufacturer torque specifications for the joint being assembled.
