Value Collection 88546742 Hex Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 88546742 is a 5/16-18 UNC hex socket cap screw designed for secure mechanical fastening in structural and machine assembly applications. The screw measures 1 inch in length under the head and is fully threaded, providing consistent clamping force along the entire shank. Constructed from alloy steel with a black oxide finish, it offers solid corrosion resistance and surface hardness suited for demanding shop and field conditions. Drive engagement is a 1/4 inch hex socket, compatible with standard Allen keys and hex bit drivers. Sold in a pack of 13.

This fastener is used across a wide range of trade and industrial applications including HVAC equipment assembly, electrical enclosure mounting, plumbing fixture brackets, and general mechanical fabrication. The 5/16-18 UNC thread is a coarse-thread standard widely used in ferrous metal assemblies where vibration resistance and ease of threading are priorities. The black oxide coating reduces light reflection and provides mild corrosion protection in indoor and controlled environments. Suitable for residential and light commercial mechanical installations.

Key Features

• 5/16-18 UNC coarse thread for broad compatibility with standard tapped holes
• Fully threaded shank provides maximum grip across the entire 1 inch length under head
• Alloy steel construction delivers high tensile and shear strength
• Black oxide finish reduces surface corrosion and glare in installed applications
• 1/4 inch hex socket drive accepts standard Allen keys and power bit drivers
• Pack of 13 supports small jobs and service repairs without excess inventory

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw for use in any application requiring this thread form, drive type, and length in alloy steel with black oxide finish.

Installation Notes

Install using a 1/4 inch hex key or hex socket bit driver; avoid using worn or undersized keys that can strip the drive recess. Ensure the mating tapped hole is clean and free of debris before threading to prevent cross-threading or galling. Power down or de-energize equipment before accessing fastener locations on electrical or mechanical assemblies. Follow applicable equipment manufacturer torque guidance for structural connections.
