Value Collection 201055P Button Socket Cap Screw 10-24

Product Description

The VALUE COLLECTION 201055P is a 10-24 x 3/8 inch button socket cap screw manufactured from alloy steel with a black oxide finish. It features a low-profile button head and a 1/8 inch hex socket drive, making it well suited for applications where clearance above the fastener surface is limited. The screw is fully threaded with a UNC thread form and a Class 3A thread fit, indicating close tolerance suitable for precision assemblies. Hardness is rated at 36-43 HRC, consistent with ASTM F835 and ANSI/ASME B18.3 standards. Machinists, fabricators, and maintenance technicians install this fastener in light industrial, mechanical, and structural assemblies.

This fastener is used wherever a flush or near-flush fastening profile is required and a standard hex socket wrench is available. The black oxide coating provides mild corrosion resistance and reduces light reflection, making it a common choice in machinery enclosures, equipment panels, jigs, and fixtures. Its compact button head profile suits tight-clearance assemblies in both shop fabrication and field maintenance settings. Right-hand thread direction follows standard installation practices for the majority of mechanical assemblies.

Key Features

• Low-profile button head reduces protrusion above mating surface
• 1/8 inch hex socket drive for standard Allen wrench installation
• Alloy steel construction with 36-43 HRC hardness per ASTM F835
• Black oxide coating for mild corrosion resistance and low reflectivity
• Fully threaded 10-24 UNC thread, Class 3A fit for close-tolerance assemblies
• Conforms to ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 10-24 UNC button socket cap screw for use in any application requiring ANSI/ASME B18.3 compliant alloy steel fasteners with a button head profile.

Installation Notes

Install using a 1/8 inch hex key or Allen driver; confirm the drive tool is fully seated before applying torque to avoid rounding the socket. Ensure mating threads are clean and free of debris before installation. Black oxide coating does not replace plating or paint for outdoor or high-moisture environments; apply thread-locking compound or additional protective coating as required by the application. This fastener is typically installed by machinists, fabricators, or maintenance technicians following applicable mechanical assembly standards.
