Value Collection 354-0432-01 Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 354-0432-01 is a 1/4-20 UNC flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Measuring 2 inches in overall length and partially threaded, it features a T30 Torx Plus drive and an 82-degree flat head geometry. Constructed from alloy steel with a black oxide finish, this screw meets ASME/ANSI B18.3 and ASTM F835 standards. It is suited for mechanical assemblies, fixtures, and equipment where a low-profile head and secure torque transfer are required. Weighing approximately 0.027 pounds per unit, it is sold individually with a minimum order quantity of 100 units.

This fastener is used in a wide range of industrial, commercial, and mechanical applications where a countersunk head must sit flush with or below the mating surface. Common install scenarios include machine frames, brackets, enclosures, jigs, and structural assemblies that see moderate to high clamping loads. The Torx Plus drive reduces cam-out risk compared to hex socket alternatives, making it a practical choice for high-cycle or production assembly environments. The black oxide finish provides a mild level of corrosion resistance suitable for indoor or controlled environments.

Key Features

• 1/4-20 UNC thread with 2-inch overall length and partial threading
• 82-degree flat head profile for flush or countersunk installations
• T30 Torx Plus drive for improved torque transfer and reduced cam-out
• Alloy steel construction for high tensile strength in demanding assemblies
• Black oxide finish for mild corrosion resistance and low-reflectance appearance
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 1/4-20 UNC flat socket cap screw suitable for use in any application requiring an 82-degree countersunk Torx Plus fastener conforming to ASME/ANSI B18.3 and ASTM F835 specifications.

Installation Notes

Installation is typically performed by machinists, millwrights, or mechanical assembly technicians using a T30 Torx Plus driver or bit. The mating countersink should be machined to an 82-degree included angle to ensure proper head seating. Verify thread engagement depth and ensure the countersink diameter matches the screw head before final torque. Follow applicable equipment or assembly specifications for torque values, as none are specified for this fastener in the available product data.
