Value Collection 211024PR Flat Socket Cap Screw 5-40

Product Description

The VALUE COLLECTION 211024PR is a flat socket cap screw designed for flush or countersunk fastening applications in metal assemblies. It features an 82-degree flat head profile and a 5/64-inch hex socket drive, requiring an Allen key or hex bit for installation. The fastener is fully threaded along its 1/2-inch overall length and uses a No. 5-40 UNC thread form. Constructed from alloy steel with a black oxide finish, it provides moderate corrosion resistance in dry or lightly protected environments. This screw is sized for compact mechanical assemblies where a low-profile head is required. Machinists, maintenance technicians, and mechanical assemblers are the typical end users.

This fastener is suited for light-duty machine assembly, instrument panels, small enclosures, and mechanical sub-assemblies where a countersunk socket head is preferred over a raised-head fastener. The No. 5-40 UNC thread size is common in precision machining and light mechanical work. The black oxide finish provides a clean, uniform appearance and is appropriate for interior or protected-environment applications. It is sold individually but carries a minimum order quantity of 100 pieces.

Key Features

• 82-degree flat head seats flush in standard countersunk holes for a low-profile finish
• 5/64-inch hex socket drive compatible with standard Allen keys and hex drivers
• Fully threaded along the entire 1/2-inch length for maximum thread engagement
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F835 fastener standards
• Black oxide finish provides mild corrosion resistance and a uniform dark appearance
• No. 5-40 UNC thread standard suits precision and light mechanical assembly work

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for any application requiring a No. 5-40 UNC fully threaded flat socket cap screw conforming to ASME/ANSI B18.3 and ASTM F835 standards.

Installation Notes

Installation is performed by machinists or mechanical technicians using a 5/64-inch hex key or compatible power driver bit. Ensure the mating countersink is machined to an 82-degree included angle to achieve proper head seating. De-energize and lockout any equipment before installing or removing fasteners in live assemblies. Do not exceed the rated mechanical limits of the No. 5-40 thread form; overtightening alloy steel screws in soft substrates can strip threads.
