Value Collection 201005PR Button Socket Cap Screw 1-72

Product Description

The VALUE COLLECTION 201005PR is a button socket cap screw designed for precision fastening applications where a low-profile head and high clamping strength are required. Manufactured from alloy steel with a black oxide finish, this screw measures 1/8 inch in length under the head and carries a 1-72 UNF thread designation. It is fully threaded and conforms to ANSI/ASME B18.3 and ASTM F835 standards. A hex socket drive allows for high torque application in tight spaces. Hardness is rated at 36 to 43 HRC, making it suitable for demanding mechanical assemblies. This fastener is installed by machinists, maintenance technicians, and precision assembly professionals.

This screw is used in light-duty mechanical assemblies, instrument panels, electronics enclosures, and precision machinery where a flush or near-flush head profile is needed. The 1-72 thread size is a fine-pitch Unified National Fine designation, common in small-diameter fastening applications found in aerospace, industrial equipment, and electronic device assembly. The black oxide coating provides mild corrosion resistance and reduces light reflection in optical or instrument applications.

Key Features

• 1-72 UNF fully threaded, right-hand thread direction with Class 3A thread fit for precise engagement
• Button head profile keeps installed height low at 0.039 inches, ideal for clearance-critical assemblies
• Alloy steel construction with 36 to 43 HRC hardness for strong clamping force in small-diameter applications
• Black oxide finish for mild corrosion resistance and reduced surface reflectivity
• Hex socket drive allows torque application in confined spaces with standard Allen keys
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-spec fastener for mechanical assemblies requiring a 1-72 UNF button socket cap screw per ANSI/ASME B18.3 dimensional standards.

Installation Notes

Installation is performed by machinists or assembly technicians using a correctly sized hex key or Allen driver. Power down or de-energize any equipment before servicing fasteners in electrical or electronic enclosures. Do not exceed the rated thread engagement depth for the mating material, as thread stripping risk increases with fine-pitch small-diameter screws. Follow applicable ASME or equipment manufacturer torque guidance for the mating material.
