Value Collection 353-0608-01 Button Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 353-0608-01 is a button head socket cap screw designed for fastening applications where a low-profile head and high clamping strength are required. This screw features a 3/8-16 unified coarse right-hand thread and a 1/2-inch length under the head. It is driven with an IP45 Torx Plus drive, which provides improved torque transfer and reduced cam-out compared to standard hex socket drives. The alloy steel construction is heat treated to a hardness of 39 to 44 HRC, and the black oxide finish provides mild corrosion resistance and a clean, low-reflectance appearance. It is used by machinists, millwrights, maintenance technicians, and mechanical contractors in both industrial and commercial settings.

This fastener suits applications where a flush or low-profile fastener head is preferred over a standard hex cap screw, such as machine guards, fixtures, panels, and mechanical assemblies. The fully threaded shank and Class 3A thread fit ensure tight tolerances and consistent engagement across compatible tapped holes. Conformance to ANSI/ASME B18.3 and ASTM F835 standards makes it suitable for use in engineered assemblies where documented fastener specifications are required.

Key Features

• 3/8-16 UNC Class 3A thread for precise fit and strong thread engagement
• IP45 Torx Plus drive reduces cam-out and allows higher installation torque
• Alloy steel with 39 to 44 HRC hardness for high tensile and shear strength
• Black oxide coating provides mild corrosion resistance and low-reflectance finish
• Fully threaded shank maximizes thread engagement in shallow or thin material
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard replacement or equivalent for 3/8-16 button socket cap screws in tapped-hole applications conforming to ANSI/ASME B18.3 specifications.

Installation Notes

Installation requires an IP45 Torx Plus bit or driver insert rated for the applied torque. Verify that the mating tapped hole is clean, free of debris, and cut to a Class 2B or 3B tolerance before installation. Always de-energize and lock out any machinery before servicing fasteners in live mechanical assemblies. Do not substitute a standard Torx bit for the Torx Plus drive, as it may damage the drive recess.
