Value Collection 202975C Hex Head Cap Screw 3/8-16 X 1-1/4 in

Product Description

The VALUE COLLECTION 202975C is a hex head cap screw in 3/8-16 UNC thread with a 1-1/4-inch length under the head. Manufactured from Grade 316 stainless steel, this fastener delivers strong corrosion resistance in wet, chemical, and marine environments. The 9/16-inch hex drive accepts standard hex wrenches and sockets for reliable installation torque. It is used across HVAC, plumbing, electrical, and pool equipment applications wherever a corrosion-resistant threaded fastener is required in an inch-standard assembly.

This cap screw suits residential and light commercial applications where exposure to moisture, chlorine, salt air, or mild chemicals makes carbon steel fasteners inadequate. Typical installations include pool equipment enclosures, outdoor condenser and air handler frames, pump and valve flanges, and other assemblies where long-term corrosion resistance is critical. The UNC thread form is the standard inch coarse-thread specification, making this screw compatible with the vast majority of tapped holes and nuts in inch-system mechanical assemblies found throughout the trades.

Key Features

• Grade 316 stainless steel construction for superior resistance to chlorides and corrosive environments
• 3/8-16 UNC coarse thread for broad compatibility with inch-standard tapped holes and hex nuts
• 1-1/4-inch length under head suits medium-depth fastening applications
• 9/16-inch hex drive accepts standard wrenches and impact sockets
• Inch measurement system for direct fit in standard trade and OEM assemblies

Compatibility

Designed as an OEM-style replacement or standard-service fastener for any inch-system assembly requiring a 3/8-16 UNC hex head cap screw in a corrosion-resistant material grade.

Installation Notes

Installation is performed by licensed mechanics, plumbers, electricians, or HVAC technicians depending on the application. De-energize electrical equipment and shut off fluid systems before replacing fasteners on live assemblies. Use a calibrated torque wrench when fastener preload is critical to joint integrity. Avoid mixing stainless steel fasteners with dissimilar metals in submerged or highly conductive environments to minimize galvanic corrosion risk.
