Value Collection -33699-5 Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION -33699-5 is a hex socket cap screw designed for high-strength fastening applications in mechanical assembly, maintenance, and fabrication work. It features a 3/4-10 UNC thread and a 5/8-inch hex drive socket head. The fastener is manufactured from alloy steel and finished with a black oxide coating, which provides a degree of corrosion resistance and reduces light reflection. The partial threading allows for stronger grip in through-bolt and clearance-hole applications. This type of screw is typically installed by machinists, millwrights, and maintenance technicians working on machinery, fixtures, and structural assemblies.

This cap screw is suited for medium to heavy-duty industrial and mechanical applications where a recessed hex drive is preferred over an external-hex fastener. The 3/4-10 UNC thread form is a coarse-thread standard commonly used in steel and iron assemblies. The 5-inch length under head accommodates thick material stacks and deep clearance applications. It conforms to ASME/ANSI B18.3 dimensional standards and ASTM A574 mechanical property requirements, making it appropriate for structural and load-bearing fastening.

Key Features

• 3/4-10 UNC coarse thread for reliable engagement in steel and iron substrates
• 5-inch length under head suits thick material stacks and deep assemblies
• 5/8-inch hex socket drive for use with standard hex keys and socket wrenches
• Partially threaded shank provides stronger shear resistance at the joint interface
• Alloy steel construction meets ASTM A574 mechanical property requirements
• Black oxide finish reduces surface reflectivity and provides mild corrosion protection

Compatibility

Designed as a standard replacement or stock fastener for industrial and mechanical assemblies requiring a 3/4-10 UNC hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 5/8-inch hex key or socket driver. De-energize and lock out all equipment before fastener installation or removal in live machinery per applicable OSHA lockout/tagout procedures. Apply thread-locking compound or appropriate torque per the equipment manufacturer's specifications for the joint. Inspect threads for damage or contamination before installation to ensure proper seating and clamping force.
