Value Collection 701185PR Button Socket Cap Screw 3/8-24

Product Description

The VALUE COLLECTION 701185PR is a fully threaded button socket cap screw designed for applications requiring a low-profile head with high clamping strength. Manufactured from alloy steel with a black oxide coating, this fastener meets ANSI/ASME B18.3 and ASTM F835 standards. It features a 3/8-24 UNF thread form, a 7/32 hex socket drive, and a 1-1/2 inch length under head. Hardness is rated at 36-43 HRC, making it suitable for demanding mechanical assemblies. Licensed trade and industrial professionals install this screw where flush or near-flush fastening is needed without sacrificing tensile performance.

This button socket cap screw is appropriate for use in machinery, fixtures, tooling, and structural assemblies where a domed, low-profile head is preferred over a standard hex cap or flat head. The fine UNF thread pitch offers improved vibration resistance and is well suited to metal-on-metal fastening in tight-tolerance applications. It is a practical choice for maintenance, repair, and fabrication work across manufacturing and industrial environments.

Key Features

• Button head profile provides a low-profile, rounded appearance with broad bearing surface
• 3/8-24 UNF fine thread for improved vibration resistance and precise torque control
• 7/32 hex socket drive for use with standard hex keys or Allen drivers
• Alloy steel construction with 36-43 HRC hardness rating for high-load applications
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or standard replacement fastener for machinery, fixtures, and assemblies requiring a 3/8-24 UNF button socket cap screw with a 1-1/2 inch length under head per ANSI/ASME B18.3.

Installation Notes

Installation is performed with a 7/32 hex key or matching socket bit. Always ensure the mating threaded hole is clean and free of debris before driving the screw. Apply thread-locking compound if the assembly is subject to vibration or dynamic loading. Follow applicable mechanical and structural codes for torque and fastener selection in your jurisdiction.
