Value Collection 204187 Hex Head Cap Screw 3/4-10 X 4 in 316 Ss

Product Description

The VALUE COLLECTION 204187 is a 3/4-10 UNC hex head cap screw measuring 4 inches in length under the head, manufactured from Grade 316 stainless steel. The 1-1/8 inch hex drive accepts standard hex sockets and wrenches. Grade 316 stainless steel provides enhanced corrosion resistance compared to 304, making this fastener well suited for wet, chemical, or marine environments. It is installed by maintenance technicians, millwrights, pipefitters, and mechanical contractors in applications where fastener integrity in corrosive conditions is a priority.

This screw is commonly used in industrial equipment assembly, mechanical systems, pipe flange connections, pump housings, and structural bracketing where exposure to moisture, chlorides, or mild chemicals demands a corrosion-resistant fastener. The UNC thread form is the standard coarse-thread series for inch-system fasteners, ensuring broad compatibility with tapped holes and standard hex nuts across trade and industrial applications.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in wet and chemical environments
• 3/4-10 UNC coarse thread for reliable engagement and ease of assembly
• 4 inches length under head for deep-grip fastening applications
• 1-1/8 inch hex head accepts standard hex sockets and open-end wrenches
• Inch system dimensions throughout for straightforward compatibility with standard hardware

Compatibility

Designed for use in standard 3/4-10 UNC tapped holes and with 3/4-10 hex nuts across industrial, mechanical, and plumbing applications requiring Grade 316 stainless steel fasteners.

Installation Notes

Installation is performed by hand-starting the screw into the tapped hole before applying a torque wrench or socket driver to seat it properly. Power down or de-energize any equipment and relieve system pressure before replacing fasteners in live mechanical assemblies. Anti-seize compound is commonly applied to stainless steel threads to prevent galling during installation and future removal. Follow applicable mechanical and structural codes for torque requirements based on joint design.
