Value Collection -33699-51/2 Hex Socket Cap Screw 3/4-10

Product Description

The VALUE COLLECTION -33699-51/2 is a hex socket cap screw engineered for high-strength fastening applications in industrial and mechanical assemblies. It features a 3/4-10 UNC thread size with a 5-1/2 inch length under head and is partially threaded to allow clamping force at the shank. The 5/8 inch hex drive accepts a standard hex key or Allen-style socket driver. Constructed from alloy steel and finished with a black oxide coating, this screw delivers solid tensile strength and moderate corrosion resistance in controlled environments. It conforms to ASME/ANSI B18.3 and ASTM A574 standards, making it a recognized choice for structural and machine fastening work.

This cap screw is suited for use in machine tool assemblies, fixture building, heavy equipment maintenance, and structural steel fabrication where a high-strength, socket-drive fastener is required. The partial threading is appropriate for applications where bolt shank grip length matters and thread engagement at the clamped joint must be controlled. Maintenance technicians, millwrights, and industrial mechanics commonly use this type of fastener when torquing into tapped holes in steel or iron components.

Key Features

• 3/4-10 UNC thread size for use in standard unified coarse tapped holes
• 5-1/2 inch length under head with partial threading for controlled grip length
• 5/8 inch hex drive compatible with standard hex keys and socket drivers
• Alloy steel construction meets ASTM A574 high-strength cap screw requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any tapped hole with a 3/4-10 UNC thread form, typical of machine frames, fixtures, and heavy mechanical assemblies.

Installation Notes

Installation is performed with a 5/8 inch hex key or hex socket driver. Ensure the mating tapped hole is clean, undamaged, and cut to 3/4-10 UNC specification before driving. De-energize or lock out any machinery before servicing fasteners on live equipment per applicable OSHA lockout/tagout procedures. Do not substitute an undersized drive tool, as rounding the socket recess will require extraction and screw replacement.
