Value Collection 201077PR Button Socket Cap Screw 10-32

Product Description

The VALUE COLLECTION 201077PR is a button socket cap screw designed for applications where a low-profile fastening head is required with the driving strength of an internal hex socket. Manufactured from alloy steel with a black oxide finish, this fastener meets ANSI/ASME B18.3 and ASTM F835 standards. It features a 10-32 UNF thread in a 3A fit class and measures 7/8 inches in length under the head. The button head profile reduces protrusion above the mating surface, making it a practical choice for machine assemblies, enclosures, brackets, and equipment panels where clearance is limited.

This screw is suited for light- to medium-duty mechanical assemblies across industrial, commercial, and maintenance applications. The 10-32 UNF thread is a standard size found in instrument panels, electronic enclosures, machine frames, and precision equipment. The black oxide coating provides mild corrosion resistance and reduces light reflection on exposed fastener surfaces. Machinists, millwrights, equipment technicians, and maintenance professionals regularly use this fastener size in both production and repair contexts.

Key Features

• Button head profile provides low clearance above mating surface
• 1/8 inch hex socket drive for standard allen key or hex bit installation
• 10-32 UNF right-hand thread in 3A fit class for precise thread engagement
• Alloy steel construction with hardness rating of 36-43 HRC
• Black oxide finish for mild corrosion resistance and low-glare appearance
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-fit fastener for any application requiring a 10-32 UNF fully threaded button socket cap screw with a 7/8 inch length under head.

Installation Notes

Installation is performed with a 1/8 inch hex key or hex socket bit driver. Power down or de-energize any equipment before accessing fastener locations on live assemblies. Do not exceed the torque capacity appropriate for a 10-32 alloy steel fastener in the receiving material. Inspect threads in the mating component before installation to confirm thread class compatibility.
