Value Collection 211006PR Flat Socket Cap Screw 1-72 Unf

Product Description

The VALUE COLLECTION 211006PR is a flat socket cap screw designed for precision fastening in tight clearance applications. It features a countersunk flat head driven by a hex socket and is fully threaded along its 3/16-inch overall length. The screw is machined from alloy steel and finished with black oxide, which provides moderate corrosion resistance and reduces light reflection on finished assemblies. Thread specification is 1-72 UNF per the inch measurement system. This fastener is typically installed by machinists, maintenance technicians, and trade professionals working on mechanical assemblies, enclosures, and instrumentation fixtures where a flush surface finish is required.

The 211006PR is suited for applications requiring a flush-mount fastener in confined spaces where standard pan or button head screws would protrude. Common uses include electronic enclosures, small mechanical subassemblies, optical mounts, and precision equipment panels. The fine UNF thread pitch provides strong clamping force in thinner materials. The black oxide finish makes it a practical choice in assemblies where surface glare or corrosion from light exposure is a concern. This screw is sold in multiples of 100 units minimum order quantity.

Key Features

• Flat countersunk head profile allows flush or below-surface seating in mating parts
• Hex socket drive provides high torque transfer in confined installation spaces
• Fully threaded 3/16-inch overall length maximizes thread engagement in thin materials
• Alloy steel construction delivers strength suitable for mechanical fastening applications
• Black oxide finish offers light corrosion resistance and a low-reflectance appearance
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style and general-purpose replacement flat socket cap screw for applications specifying a 1-72 UNF fully threaded flat head hex socket fastener per ASME/ANSI B18.3.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician using a properly sized hex key or hex bit driver matched to the socket to avoid cam-out on the small drive recess. Ensure the mating part is drilled and countersunk to the correct flat-head angle before installation. De-energize any equipment and follow applicable lockout/tagout procedures before replacing fasteners in live electrical or mechanical assemblies. Avoid over-torquing small-diameter fine-thread screws, as alloy steel at this thread size can be susceptible to shear at excessive torque.
