Value Collection 353-0408-01 Button Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 353-0408-01 is a 1/4-20 button socket cap screw designed for secure, low-profile fastening in mechanical assemblies, fixtures, and equipment enclosures. Manufactured from alloy steel with a black oxide finish, it meets ANSI/ASME B18.3 and ASTM F835 standards. The screw measures 1/2 inch in length under the head and uses a Torx Plus IP27 drive, which provides improved torque transfer and reduced cam-out compared to standard hex drives. Hardness is rated at 39-44 HRC, making it suitable for high-stress applications. The thread is 1/4-20 UNC with a Class 3A fit and right-hand direction. Sold individually with a minimum order quantity of 100 pieces.

This button socket cap screw is used in a wide range of industrial, OEM, and maintenance applications where a rounded, low-profile head is required to clear adjacent components or provide a flush appearance. Common applications include machine frames, panel assemblies, jigs, fixtures, and equipment housings. The black oxide finish provides mild corrosion resistance and a uniform appearance. It is installed by mechanical technicians and assembly professionals in both production and field service environments.
