Value Collection R63263420 Hex Cap Screw 3/8-24 18-8 Ss

Product Description

The VALUE COLLECTION R63263420 is a hex head cap screw designed for secure mechanical fastening in a wide range of trade and industrial applications. It features a 3/8-24 UNF (Unified Fine) thread and measures 1-3/4 inches under the head. The fastener is partially threaded, which allows it to clamp mating parts with a smooth shank section before the threaded engagement begins. Constructed from 18-8 stainless steel with an uncoated finish, it delivers solid corrosion resistance without any surface treatment that could interfere with torque specifications or electrical continuity. Plumbers, HVAC technicians, and general mechanical contractors regularly spec this fastener type for equipment mounting and structural connections.

This screw is well suited for use in wet or corrosion-prone environments where carbon steel fasteners would degrade. Common install scenarios include mounting HVAC equipment brackets, plumbing fixture hardware, electrical enclosure assemblies, and pool or spa equipment where moisture exposure is a concern. The fine thread pitch of 24 threads per inch provides enhanced vibration resistance compared to coarse thread fasteners of the same diameter, making it a practical choice for mechanical equipment subject to continuous operation or vibration.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet and outdoor environments
• 3/8-24 UNF fine thread for improved vibration resistance and precise torque control
• Partially threaded shank for solid clamping of mating components
• 1-3/4 inch length under head suits medium-depth fastening applications
• Uncoated finish maintains dimensional tolerances and avoids coating buildup in tapped holes
• Hex head drive compatible with standard hex wrenches and sockets

Compatibility

Designed as a standard UNF hex head cap screw for use in any 3/8-24 tapped hole or with a compatible 3/8-24 hex nut, suitable for general mechanical, HVAC, plumbing, and electrical equipment fastening applications.

Installation Notes

Installation is performed by any qualified trade professional using a standard hex wrench or socket set sized for a 3/8 inch hex head fastener. Confirm the mating thread is clean and free of debris before installation to prevent galling, which is a known risk with stainless steel fasteners. Apply an appropriate anti-seize compound to the threads prior to installation to reduce the risk of thread galling and facilitate future removal. Always verify that the fastener grade and material are appropriate for the load, environment, and applicable mechanical or electrical codes before final assembly.
