Value Collection 354-5504-01 Flat Socket Cap Screw 5-40

Product Description

The VALUE COLLECTION 354-5504-01 is a flat socket cap screw designed for precision fastening applications requiring a flush or countersunk seating profile. Sized at 5-40 UNC x 1/4 inch overall length and fully threaded, it uses a Torx Plus T10 drive for higher torque transfer and reduced cam-out compared to standard hex sockets. The 82-degree flat head seats cleanly in countersunk holes machined to ASME/ANSI B18.3 and ASTM F835 standards. Constructed from alloy steel with a black oxide finish, this screw offers a balance of hardness and mild corrosion resistance suitable for indoor mechanical assemblies.

This screw is used in light-duty mechanical assemblies, electronic enclosures, instrumentation panels, and precision equipment where a low-profile flush fastener is required. The fine 40-thread-per-inch pitch provides good holding strength in thin or tapped metal stock. Minimum order quantity is 100 pieces. Typical installers include mechanical assemblers, machinists, and equipment technicians working on close-tolerance components.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• Torx Plus T10 drive reduces cam-out and allows higher torque application
• Fully threaded 5-40 UNC x 1/4 inch overall length for maximum thread engagement
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F835 standards
• Black oxide finish provides mild corrosion resistance for indoor use

Compatibility

Designed as an OEM-style replacement or standard-fit fastener for applications requiring a 5-40 UNC fully threaded flat socket cap screw with an 82-degree countersunk head profile.

Installation Notes

Installation is performed by mechanical assemblers or technicians using a Torx Plus T10 driver or bit. Ensure the mating countersink is machined to 82 degrees to achieve proper head seating and flush finish. Do not overtighten in tapped blind holes, as the fine thread pitch can be susceptible to stripping in soft materials. Follow applicable fastener torque guidelines from the equipment manufacturer or relevant ASME standards for the specific assembly.
