Value Collection 350-2420-61 Socket Cap Machine Screw

Product Description

The VALUE COLLECTION 350-2420-61 is a fully threaded socket cap head machine screw designed for high-strength fastening applications in mechanical assemblies, fixtures, and equipment. It features a 1/4-28 UNF thread with a 1-1/4 inch length under the head and a T30 Torx drive, requiring a standard T30 driver or bit for installation. Manufactured from alloy steel with a black oxide finish, this screw provides corrosion resistance and reduced light reflection in service environments. It meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 standards, making it suitable for precision and defense-grade assemblies.

This screw is used in a wide range of industrial, mechanical, and trade applications where a tamper-resistant or high-torque Torx drive is preferred over hex or Phillips styles. The socket cap head profile keeps the fastener low-profile against the work surface. Typical use cases include machine guarding, equipment enclosures, hydraulic manifolds, and structural brackets where fine-thread engagement and controlled torque are required. This item is sold individually with a minimum order quantity of 100 pieces.

Key Features

• 1/4-28 UNF fine thread for precise engagement and vibration resistance
• 1-1/4 inch length under head, fully threaded
• T30 Torx drive for high torque transfer and reduced cam-out
• Alloy steel construction for tensile strength in demanding applications
• Black oxide finish for mild corrosion resistance and low reflectivity
• Meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 standards

Compatibility

Designed as a standard 1/4-28 UNF socket cap head machine screw suitable for use in any application requiring an ANSI B18.3-compliant fastener with a T30 Torx drive.

Installation Notes

Installation should be performed by a qualified mechanic or technician using a T30 Torx driver or bit. Ensure the mating threaded hole is clean and free of debris before driving the screw. Apply appropriate thread preload per the assembly specification; do not overtorque alloy steel fine-thread fasteners in softer base materials. Follow applicable ASME or military fastener standards when used in structural or defense-rated assemblies.
