Value Collection MS16997-100 Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION MS16997-100 is a hex socket cap screw designed for secure fastening in mechanical, industrial, and trade applications. It features a 3/8-16 UNC thread and a 1-1/4 inch length under head, with full threading along the shank. Manufactured from 4037-grade alloy steel and finished with a yellow cadmium plating, this screw offers solid corrosion resistance and mechanical strength. Drive engagement is achieved with a 5/16 inch hex socket. Licensed technicians, millwrights, and maintenance professionals use this fastener in assemblies where a clean socket-drive installation is required.

This fastener is suited for a wide range of industrial and mechanical installations where 3/8-16 UNC threading is specified. The fully threaded shank makes it appropriate for through-hole applications and thinner material assemblies. Its alloy steel construction handles moderate to high load environments. The yellow cadmium coating provides additional corrosion protection, making it a practical choice in environments with exposure to moisture or mild chemicals. It is produced to ASME B18.3 standards.

Key Features

• 3/8-16 UNC thread for broad fastener compatibility in standard inch-series applications
• 1-1/4 inch length under head, fully threaded for maximum thread engagement
• 4037-grade alloy steel construction for mechanical strength and durability
• Yellow cadmium finish provides corrosion resistance in moisture-exposed environments
• 5/16 inch hex socket drive for precise torque application and clean installation
• Manufactured to ASME B18.3 fastener standard

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw per ASME B18.3, suitable for use in any application specifying this thread size, drive type, and length under head.

Installation Notes

Installation should be performed by qualified technicians using a calibrated 5/16 inch hex key or socket driver. Always de-energize or lock out equipment before replacing fasteners in mechanical assemblies. Confirm thread engagement and torque to the assembly manufacturer's specifications. Avoid over-torquing, which can stress alloy steel fasteners beyond their yield point.
