Value Collection -33614-5 Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION -33614-5 is a hex socket cap screw designed for secure, high-torque fastening in mechanical assemblies, tooling fixtures, and structural connections. It features a 1/4-20 UNC thread with a 6-inch length under head and is partially threaded to allow for precise clamping without thread engagement across the full shank. The 3/16-inch hex drive accepts a standard Allen key or hex bit driver. Manufactured from alloy steel with a black oxide finish coating, this fastener delivers solid tensile strength and moderate corrosion resistance in dry or lightly protected environments. It meets ASME/ANSI B18.3 and ASTM A574 standards. Sold in a package of 10.

This screw is suited for machine tool builds, jig and fixture fabrication, equipment maintenance, and general industrial assembly where a recessed-drive cap screw is required. The partial threading is particularly useful in applications where the unthreaded shank must pass through a clearance hole in one component before engaging a tapped hole in a second. It is commonly installed by machinists, millwrights, and maintenance technicians across manufacturing and industrial service settings.

Key Features

• 1/4-20 UNC thread for compatibility with standard tapped holes and hardware
• 6-inch length under head for deep-reach or stacked-component fastening
• Partially threaded shank allows clamping force without full-length thread engagement
• 3/16-inch hex socket drive accepts standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 for high tensile strength
• Black oxide finish provides a low-reflectance surface and light corrosion protection

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for any tapped or threaded insert accepting a 1/4-20 UNC fastener in industrial, mechanical, or structural assemblies.

Installation Notes

Installation requires a 3/16-inch hex key or Allen-drive bit. Ensure the tapped receiving hole is clean and free of debris before installation. De-energize and lock out any machinery before servicing fasteners on powered equipment. Do not exceed the rated torque range for 1/4-20 alloy steel cap screws as specified by the applicable equipment manufacturer or ASME standards.
