Value Collection 211008PR Flat Socket Cap Screw 1-72 3/8 in

Product Description

The VALUE COLLECTION 211008PR is a flat socket cap screw designed for precision fastening in applications where a flush or countersunk head profile is required. Sized at number 1-72 UNF thread with a 3/8 inch overall length, this screw is fully threaded and features an 82-degree flat head with a hex socket drive. It is machined from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces surface glare. This fastener is appropriate for mechanical assemblies, instrument enclosures, and light industrial equipment where a low-profile head is necessary and clearance is limited.

This screw is suited for small-scale assemblies in industries including electronics, precision machinery, and general manufacturing. The number 1-72 thread designation falls within the Unified National Fine thread series, making it appropriate for applications requiring fine thread engagement in thin or delicate materials. Installers and machinists working on instrumentation panels, fixtures, or compact mechanical assemblies will find this screw a standard choice for countersunk socket drive applications.

Key Features

• 82-degree flat head profile seats flush in standard countersunk holes
• Hex socket drive allows torque application in tight spaces with an Allen wrench
• Fully threaded 3/8 inch length maximizes thread engagement across the full shank
• Alloy steel construction provides strength appropriate for light to medium load fastening
• Black oxide finish offers mild corrosion resistance and a low-reflectance appearance
• Conforms to ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-stock flat socket cap screw for applications specifying a number 1-72 UNF fully threaded flat head hex socket fastener per ASME/ANSI B18.3 and ASTM F835.

Installation Notes

Installation requires a properly sized hex key or Allen driver matched to the socket head to avoid stripping. Ensure the mating hole is countersunk to an 82-degree angle for correct head seating. Power down any equipment before fastener replacement in electrical or mechanical assemblies. Thread engagement and torque should follow the assembly specification for number 1 alloy steel fasteners per applicable engineering standards.
