Value Collection 353-0612-01 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 353-0612-01 is a button socket cap screw designed for structural and mechanical fastening applications where a low-profile head and high clamping strength are required. The screw features a 3/8-16 thread size with a 3/4-inch length under the head and is manufactured from alloy steel with a black oxide finish. Drive engagement is through a Torx Plus IP45 (TP45) socket, which delivers higher torque transfer and reduced cam-out compared to standard hex drives. Hardness is rated at 39-44 HRC per ASTM F835 requirements, making this fastener suitable for high-stress assemblies.

This button socket cap screw is used in general industrial, mechanical, and structural applications where a flush or low-profile fastener head is preferred over a standard socket head cap screw. The fully threaded 3A fit class ensures precise thread engagement in both tapped holes and nuts. The black oxide coating provides mild corrosion resistance and reduces light reflection in precision or aesthetic assemblies. Machinists, millwrights, and maintenance technicians commonly use this fastener in machine frames, fixtures, guards, and equipment panels.

Key Features

• Torx Plus IP45 (TP45) drive for high torque transfer and reduced cam-out
• Alloy steel construction rated 39-44 HRC per ASTM F835
• Black oxide finish for mild corrosion resistance and low reflectivity
• Button head profile at 0.199 inches head height for low-clearance installations
• Fully threaded, right-hand thread direction

Compatibility

Designed as an OEM-style replacement or direct-use fastener conforming to ANSI/ASME B18.3 and ASTM F835 standards for 3/8-16 button socket cap screw applications.

Installation Notes

Installation requires a Torx Plus IP45 (TP45) drive bit or key - do not substitute a standard Torx T45 driver, as the drive geometry differs. Always verify tapped hole depth and thread condition before installation. Torque to the value specified by the equipment manufacturer or applicable structural standard for Grade alloy steel fasteners of this diameter. Follow all applicable safety lockout and tagout procedures before servicing equipment.
