Value Collection 353-0616-01 Button Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 353-0616-01 is a 3/8-16 button socket cap screw designed for high-strength fastening applications in industrial, mechanical, and fabrication environments. It features a Torx Plus drive (IP45/TP45) with a 7/32 inch drive size, providing improved torque transfer and reduced cam-out compared to standard hex socket drives. The screw is fully threaded with a unified coarse right-hand thread (UNRC, Thread Fit Class 3A) and meets ANSI/ASME B18.3 and ASTM F835 standards. Hardness is rated at 39-44 HRC. This fastener is typically installed by machinists, millwrights, and maintenance technicians working with metal assemblies and structural components.

This button cap screw suits applications where a low-profile head is required and high clamping load is critical. The 1 inch length under head and 3/8-16 thread size make it appropriate for medium-duty structural and mechanical assemblies. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it suitable for both interior mechanical assemblies and controlled-environment installations. It is sold in multiples of 100 units per order with a package quantity of 1.

Key Features

• Torx Plus IP45/TP45 drive reduces cam-out and improves torque transfer over standard hex drives
• Alloy steel construction with 39-44 HRC hardness for high-strength fastening
• Black oxide finish for mild corrosion resistance and low-reflectivity surface
• Fully threaded UNRC 3/8-16 right-hand thread, Thread Fit Class 3A
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards
• Low-profile button head design for flush or recessed installation in tight clearance areas

Compatibility

Designed as a standard 3/8-16 UNC button socket cap screw compatible with tapped holes and threaded inserts conforming to UNRC thread standards in industrial and mechanical assemblies.

Installation Notes

Installation requires a Torx Plus IP45 driver bit or socket; standard Torx bits may fit but are not recommended as they can damage the drive recess or slip under high torque. Power down and de-energize any equipment before fastening components in electromechanical assemblies. Follow applicable torque specifications published in ANSI/ASME B18.3 for the thread size and material grade being joined. A calibrated torque wrench is recommended to avoid over-torquing the alloy steel screw into softer base materials.
