Value Collection 307186BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 307186BR is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, fabrication, and industrial maintenance. It features a 3/4-10 UNC thread size and measures 4.5 inches in length under the head. The fastener is machined from alloy steel and finished with a black oxide coating, which provides moderate corrosion resistance and reduces light glare on exposed hardware. Drive engagement is handled by a 9/16-inch hex socket, suitable for standard hex key sets and socket drive tools. This screw meets ASTM A574, the specification for alloy steel socket-set screws and cap screws.

This cap screw is suited for use in structural and mechanical assemblies where high tensile strength and a clean, recessed-head profile are required. Typical applications include machine frames, fixture building, tooling plates, and equipment maintenance across manufacturing, construction, and general industrial settings. The partial threading allows for precise clamping force and load distribution in bolted joints with thicker mating materials. Machinists, millwrights, and maintenance technicians commonly install this type of fastener.

Key Features

• 3/4-10 UNC thread size for high-load fastening applications
• 4.5 inches length under head with partial threading for controlled clamping
• Alloy steel construction meets ASTM A574 tensile strength requirements
• Black oxide finish provides moderate corrosion resistance and low-reflectance appearance
• 9/16-inch hex socket drive compatible with standard hex keys and socket drivers

Compatibility

Designed as a standard ASTM A574 alloy steel socket cap screw for use in any application requiring a 3/4-10 UNC partially threaded fastener with a hex socket drive.

Installation Notes

Install using a properly sized 9/16-inch hex key or socket drive tool to avoid rounding the drive recess. Ensure mating threads are clean and free of debris before installation. Apply appropriate thread lubricant or thread-locking compound as required by the joint specification. Torque to the value specified in the applicable engineering or assembly documentation for 3/4-10 ASTM A574 fasteners.
