Value Collection 211352BR Flat Socket Cap Screw 5/8-11

Product Description

The Value Collection 211352BR is a flat socket cap screw designed for use in flush or countersunk fastening applications where a low-profile head is required. It features a 5/8-11 UNC thread and a 2.5-inch overall length, with a fully threaded shank that provides consistent clamping across the full grip range. The 82-degree flat head seats flush with the work surface when used in a properly countersunk hole. The hex socket drive measures 3/8 inches across and accepts a standard hex key or bit driver. Made from alloy steel with a black oxide finish, this screw offers solid mechanical strength and mild corrosion resistance in dry or lightly oiled environments. Machinists, millwrights, and general fabricators are the typical installers.

This screw is suited for industrial assembly, machine building, tooling fixtures, and structural fabrication where a flush fastener is preferred over a raised-head cap screw. The black oxide finish reduces light reflection and provides a degree of surface protection, making it a common choice in equipment enclosures and precision machinery. The fully threaded body is particularly useful in thin-material applications or wherever thread engagement must begin close to the head. Minimum order quantity is 10 pieces.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• 5/8-11 UNC thread with 2.5-inch overall length, fully threaded
• 3/8-inch hex socket drive for secure torque transfer
• Alloy steel construction for high tensile and shear strength
• Black oxide finish for mild corrosion resistance and low reflectivity
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard UNC flat socket cap screw for use in countersunk holes sized to accept a 5/8-11 thread with an 82-degree flat head profile.

Installation Notes

Installation is typically performed by machinists or mechanical assemblers using a 3/8-inch hex key or socket bit driver. Power down or de-energize any equipment before fastener replacement or removal on live assemblies. The mating hole must be countersunk to an 82-degree included angle at the correct diameter to allow the head to seat flush. Do not use an impact driver without a torque-limiting adapter, as alloy steel screws can shear if over-driven.
