Value Collection 199629 Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 199629 is a 3/8-16 UNC hex socket cap screw designed for secure, high-torque fastening in industrial and mechanical assemblies. This fastener measures 2 inches in length under the head and accepts a 5/16 inch hex (Allen) drive. Constructed from 18-8 stainless steel, it delivers corrosion resistance suitable for wet, marine, and chemical-exposure environments. The screw is partially threaded, which is standard for cap screws in this size range, providing clamping force between joined components. Machinists, maintenance technicians, and contractors install these fasteners across a wide range of structural and equipment assembly applications.

This cap screw is used in general industrial fabrication, machinery assembly, equipment maintenance, and structural applications where a flush or low-profile socket head is required. The 3/8-16 UNC thread designation makes it compatible with standard inch-series tapped holes and nuts found throughout North American manufacturing and trade work. The 18-8 stainless construction makes it well suited for food processing, marine, and outdoor installations where carbon steel fasteners would corrode.

Key Features

• 3/8-16 UNC thread for compatibility with standard inch-series tapped holes
• 2 inch length under head provides adequate grip range for typical bolted joint applications
• 5/16 inch hex socket drive for use with standard Allen wrenches or hex bit drivers
• 18-8 stainless steel construction resists rust and corrosion in wet or chemically active environments
• Partially threaded shank for proper clamping force in standard cap screw applications
• Low-profile socket head allows installation in recessed or clearance-restricted locations

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw suitable for use with any inch-series tapped hole or nut of the same thread specification in industrial, mechanical, or structural assemblies.

Installation Notes

Install using a 5/16 inch hex key or Allen bit driver. Ensure mating threads are clean and free of debris before installation. Apply appropriate thread lubricant or anti-seize compound when fastening stainless steel screws to stainless threads to prevent galling. Follow applicable torque specifications from the equipment manufacturer or structural drawings for the joint being assembled.
