Value Collection 211005PR Flat Socket Cap Screw 1-72 Unf

Product Description

The VALUE COLLECTION 211005PR is a flat socket cap screw designed for precision fastening applications requiring a flush or countersunk head profile. The 82-degree flat head seats into a standard countersunk hole, leaving a smooth surface when fully driven. Drive engagement is via hex socket, which allows high torque transfer in tight spaces where a standard wrench cannot operate. This screw is fully threaded with a 1-72 UNF thread form, manufactured from alloy steel with a black oxide finish that provides mild corrosion resistance and reduces light reflection. Machinists, tool and die technicians, and precision assembly technicians typically install this fastener in fine-tolerance assemblies.

This screw is suited for light mechanical assemblies, instrument panels, jigs, fixtures, and precision machine components where a low-profile flush head is required. The 1-72 thread size is a fine-pitch unified thread commonly found in miniature and instrument-grade applications. The 1/8-inch overall length makes it appropriate for thin material stacks where a longer fastener would protrude or bottom out. This item is sold individually but requires a minimum order quantity of 100 units.

Key Features

• 82-degree flat head seats flush in standard countersunk holes for a smooth surface finish
• Hex socket drive enables high torque in confined spaces
• Fully threaded 1-72 UNF fine-pitch thread for precise clamping in miniature assemblies
• Alloy steel construction provides strength appropriate for precision fastener applications
• Black oxide finish offers mild corrosion resistance and low-glare appearance
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-spec fastener for any application requiring a 1-72 UNF fully threaded flat socket cap screw with an 82-degree head angle per ASME/ANSI B18.3.

Installation Notes

Installation should be performed by machinists or mechanical assemblers familiar with miniature fastener handling. Ensure the mating countersunk hole matches the 82-degree included angle before driving the screw. Use a correctly sized hex key to avoid rounding the socket drive on this small fastener. Do not exceed the torque capacity appropriate for the fastener diameter and material being joined.
