Value Collection 701179PR Button Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 701179PR is a button socket cap screw designed for fastening applications that require a low-profile head and high tensile strength. Manufactured from alloy steel with a black oxide coating, this fully threaded fastener features a 3/8-16 UNC thread and measures 2-1/2 inches under the head. Hardness is rated at 36-43 HRC, meeting ANSI/ASME B18.3 and ASTM F835 standards. The 7/32-inch hex socket drive accepts a standard hex key, making installation straightforward in confined or recessed spaces. This screw is suited for mechanical assemblies, tooling fixtures, and general industrial fastening tasks.

This fastener is commonly used in machine assembly, jig and fixture construction, and equipment maintenance where a flush or semi-flush surface is required. The button head profile sits lower than a standard socket cap head, reducing snagging and interference with adjacent components. The black oxide finish provides mild corrosion resistance and a consistent appearance, making it a practical choice for both interior mechanical and light industrial environments.

Key Features

• Button head profile provides a low-profile, snag-resistant surface for congested assemblies
• Alloy steel construction with 36-43 HRC hardness for high-strength fastening
• Black oxide coating adds mild corrosion resistance and a uniform matte finish
• 3/8-16 UNC fully threaded with a 3A thread fit class for consistent engagement
• 7/32-inch hex socket drive compatible with standard Allen or hex keys
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 3/8-16 UNC button socket cap screw for use in any application requiring ANSI/ASME B18.3 and ASTM F835 compliant fasteners in alloy steel with a black oxide finish.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson using a 7/32-inch hex key or Allen driver. Ensure mating threads are clean and free of debris before installation. Apply appropriate thread lubricant or threadlocker as required by the application. Always verify torque requirements against the engineering specification for the assembly; do not overtighten, as this can compromise thread integrity.
