Value Collection 201059PR Button Socket Cap Screw 10-24

Product Description

The VALUE COLLECTION 201059PR is a button socket cap screw designed for applications requiring a low-profile head and a secure hex socket drive. Sized at 10-24 UNC thread with a 5/8-inch length under the head, this fastener is fully threaded and manufactured from alloy steel with a black oxide coating. The black oxide finish provides moderate corrosion resistance and reduces light reflection, making it a practical choice in both mechanical assemblies and fabrication work. Hardness is rated at 36-43 HRC per ASTM F835, and thread fit class is 3A. Licensed trades and general industrial assemblers routinely specify this screw for panel mounting, machinery guards, and access covers.

This button socket cap screw suits applications where a standard hex cap screw head would protrude too far or interfere with adjacent components. The low-profile button head keeps clearance tight while the 1/8-inch hex socket drive allows torquing with standard Allen keys or hex bit drivers. It is used across light industrial, HVAC cabinet assembly, electrical enclosures, and mechanical fabrication. Conformance to ANSI/ASME B18.3 and ASTM F835 ensures dimensional consistency for production and repair environments where interchangeability matters.

Key Features

Compatibility

Designed as a standard UNC 10-24 button socket cap screw conforming to ANSI/ASME B18.3 and ASTM F835, suitable as a direct dimensional replacement in any application calling out those specifications.

Installation Notes

Install using a 1/8-inch hex key or hex socket bit driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Do not exceed the rated torque range for the 10-24 thread size and 3A fit class as specified in applicable fastener standards. Black oxide coatings offer limited corrosion protection; apply a thread lubricant or anti-seize compound where moisture exposure is a concern.
