Value Collection 40236 Hex Socket Cap Screw 3/8-24 Unf 50 Pack

Product Description

The VALUE COLLECTION 40236 is a hex socket cap screw designed for precision fastening in mechanical, industrial, and trade applications. Featuring a 3/8-24 UNF thread size with a 1/2 inch length under head, this screw is fully threaded and driven with a 5/16 inch hex key. It is manufactured from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces light reflection. This package contains 50 screws, making it suited for production work, maintenance kits, or bench stock. It meets ASME/ANSI B18.3 and ASTM A574 dimensional and strength standards.

This screw is used in general mechanical assembly, equipment maintenance, and fixture fabrication across HVAC, plumbing, electrical, and industrial trades. The fine 3/8-24 UNF thread pitch provides greater thread engagement per inch compared to coarse thread, making it well suited for thin-material fastening or applications where vibration resistance and precise clamping force are required. It installs in pre-tapped holes or with a corresponding hex nut.

Key Features

• 3/8-24 UNF fine thread for increased thread engagement and vibration resistance
• Fully threaded 1/2 inch length under head for maximum clamping flexibility
• 5/16 inch hex socket drive for use with standard Allen keys or hex-bit drivers
• Alloy steel construction meets ASTM A574 mechanical strength requirements
• Black oxide finish provides mild corrosion protection and low-glare appearance
• Pack of 50 for production, service kits, or bench stock replenishment

Compatibility

Designed as a standard OEM-style replacement or stock fastener for any application requiring a 3/8-24 UNF hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation is performed with a 5/16 inch hex key or Allen-bit driver. Always ensure the mating tapped hole or nut is clean and free of debris before installation. Do not exceed the torque capacity of the alloy steel grade; consult ASME torque tables for 3/8-24 UNF Grade 8 fasteners if a specific clamp load is required. Black oxide finish offers minimal corrosion resistance — apply thread-locking compound or anti-seize as required by the application environment.
