Value Collection MP33607 Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION MP33607 is a hex socket cap screw designed for secure, high-strength fastening in metal assemblies, machinery, and structural applications. It features a 1/4-20 UNC thread and a 3/16 inch hex drive, making it compatible with standard Allen keys and hex bit drivers. The screw measures 1-3/4 inches in length under the head and is partially threaded, which helps maintain clamping force in bolted joints. Constructed from alloy steel with a black oxide finish, it delivers corrosion resistance and a clean appearance suited for both functional and finished assemblies. Machinists, millwrights, and maintenance technicians are the primary installers of this fastener type.

This cap screw is suited for general industrial fastening, machine building, jig and fixture assembly, and equipment maintenance. It is commonly used where a low-profile, recessed-drive fastener is required to avoid interference with adjacent components. The 1/4-20 UNC thread is a widely used coarse-thread standard, compatible with tapped holes conforming to ASME/ANSI B18.3 and ASTM A574 specifications. Minimum order quantity is 25 pieces per order. Sold as a quantity of 1 per package.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes
• 1-3/4 inch length under head with partial threading to maintain joint clamping load
• 3/16 inch hex socket drive accepts standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides moderate corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any tapped hole or threaded insert conforming to ASME/ANSI B18.3 dimensional standards.

Installation Notes

Installation is performed with a 3/16 inch hex key or Allen driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Do not exceed the rated torque range for 1/4-20 alloy steel cap screws as specified by applicable fastener standards. Wear appropriate eye protection when working with high-strength fasteners under load.
