Value Collection 353-0410-01 Button Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 353-0410-01 is a button socket cap screw designed for mechanical fastening applications requiring a low-profile head and high clamping strength. Manufactured from alloy steel with a black oxide finish, this screw features a 1/4-20 UNC right-hand thread and measures 5/8 inches under the head. It is driven by a Torx Plus IP27 socket, which provides better torque transfer and reduced cam-out compared to standard hex drives. With a hardness rating of 39-44 HRC, this fastener meets ANSI/ASME B18.3 and ASTM F835 standards. It is fully threaded with a Class 3A thread fit and a head height of 0.046 inches. Licensed trade professionals and precision assembly technicians are the primary installers.

This button socket cap screw is suited for residential and commercial mechanical assemblies where a flush or near-flush fastener profile is required. The low-profile button head makes it a practical choice in tight clearance zones such as panel mounting, machine guards, fixtures, and equipment enclosures. The black oxide coating provides moderate corrosion resistance and reduces light reflection, making it appropriate for both indoor industrial environments and light-duty exposed applications. The Torx Plus drive reduces tool wear during high-volume assembly work.

Compatibility

Designed as an OEM-style replacement or standard fastener for mechanical assemblies requiring a 1/4-20 x 5/8 inch fully threaded button socket cap screw with a Torx Plus IP27 drive.

Installation Notes

Installation requires a Torx Plus IP27 driver or bit. Power down or de-energize any equipment before accessing fastener locations on live systems. Follow applicable ASME or equipment manufacturer torque specifications for 1/4-20 alloy steel fasteners. Inspect thread engagement and seating surface condition before final torque to avoid cross-threading or under-clamping.
