Value Collection 701173PR Button Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 701173PR is a button socket cap screw designed for mechanical assemblies where a low-profile head and high clamping strength are required. Manufactured from alloy steel with a black oxide coating, this screw features a 3/8-16 UNC thread and measures 1-3/4 inches under the head. The button head profile reduces snag points in tight clearance applications. Drive engagement is through a 7/32 hex socket. Hardness is rated at 36-43 HRC, meeting the mechanical requirements of ANSI/ASME B18.3 and ASTM F835. This fastener is suited for general industrial, mechanical, and structural assembly work performed by machinists, millwrights, and maintenance technicians.

This screw is used in applications where a rounded, low-profile head is preferred over a standard socket cap profile. Typical installations include machine guards, enclosures, jigs, fixtures, and light structural assemblies. The black oxide finish provides moderate corrosion resistance and reduces light reflection, making it appropriate for tooling and equipment builds where appearance and mild protection matter. The fully threaded shank and Class 3A thread fit ensure consistent engagement and torque transfer in standard tapped holes.

Key Features

• Button head profile for low clearance and reduced snag in assembled components
• Alloy steel construction rated 36-43 HRC for high tensile strength
• Black oxide coating for mild corrosion resistance and reduced glare
• 3/8-16 UNC fully threaded, Class 3A thread fit for precise engagement
• 7/32 hex socket drive for standard hex key or socket head tooling
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed for use in standard 3/8-16 UNC tapped holes in metalworking, industrial machinery, and mechanical assembly applications. Verify thread depth and hole clearance before installation.

Installation Notes

Installation is performed using a 7/32 hex key or appropriate socket driver. Ensure the mating tapped hole is clean and free of debris before threading. Power down or de-energize any equipment before fastener service on live machinery. Follow applicable torque guidelines for 3/8-16 alloy steel fasteners per your engineering specifications or applicable industry standards.
