Value Collection MP33686-4 Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION MP33686-4 is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, structural connections, and equipment maintenance. It features a 5/8-11 UNC thread size and a 4-inch length under the head with partial threading. The alloy steel construction is finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection. The 1/2-inch hex drive is engaged with a standard hex key or socket driver. This type of fastener is commonly installed by millwrights, maintenance mechanics, and machine builders.

This screw is suited for use in industrial machinery, structural steel assemblies, and heavy equipment applications where a recessed-drive, high-tensile fastener is required. The 5/8-11 UNC coarse thread pattern seats efficiently in tapped steel housings and standard threaded inserts. Partial threading allows the unthreaded shank to bear shear loads, making it appropriate for applications where alignment and shear strength matter alongside clamping force.

Key Features

• 5/8-11 UNC coarse thread for compatibility with standard tapped holes and threaded components
• 4-inch length under head for deep fastening in thick materials or stacked assemblies
• Partially threaded shank to handle shear loading alongside clamping duty
• Alloy steel construction for high tensile and yield strength
• Black oxide finish for mild corrosion resistance and low-glare surface
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as a standard hex socket cap screw for use in any application requiring a 5/8-11 UNC partially threaded fastener per ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation requires a 1/2-inch hex key or T-handle driver rated for the drive size. Ensure the mating threaded hole is clean, properly tapped to 5/8-11 UNC, and free of debris before fastening. Power down or de-energize any equipment before accessing fastened assemblies. Follow applicable torque specifications from engineering drawings or fastener manufacturer torque tables for alloy steel cap screws of this diameter.
