Value Collection R68449366 Hex Socket Cap Screw 3/4-10

Product Description

The VALUE COLLECTION R68449366 is a hex socket cap screw designed for secure, high-load fastening in industrial and mechanical assemblies. It features a 3/4-10 UNC thread size and a 4-inch length under head, making it suitable for applications that require deep thread engagement. The fastener is driven with a 5/8-inch hex key and is manufactured from 18-8 stainless steel, which provides good corrosion resistance in both indoor and outdoor environments. Machinists, millwrights, and maintenance technicians commonly install this style of screw in equipment frames, fixtures, and structural components where a clean, flush-seated fastener head is required.

This cap screw is used across a broad range of commercial, industrial, and mechanical maintenance applications. The 3/4-10 UNC thread is a standard coarse-thread designation common in structural and machine-assembly work. The 18-8 stainless steel construction makes it a practical choice for installations where moisture exposure or mild chemical contact is a concern, such as food processing equipment, marine-adjacent environments, and HVAC structural supports. It is sold individually, making it straightforward to source as a single replacement fastener.

Key Features

• 3/4-10 UNC coarse thread for strong thread engagement in standard tapped holes
• 4-inch length under head provides deep fastening reach for thick or stacked materials
• 5/8-inch hex socket drive for use with standard hex keys or socket drivers
• 18-8 stainless steel construction offers corrosion resistance in wet or mildly corrosive environments
• Recessed socket head allows flush or near-flush installation in counterbored applications

Compatibility

Designed as a standard replacement or new-installation hex socket cap screw for any application requiring a 3/4-10 UNC thread, 4-inch length under head, and 5/8-inch hex drive in 18-8 stainless steel.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 5/8-inch hex key or socket driver. Ensure the mating tapped hole is clean, undamaged, and correctly sized for 3/4-10 UNC thread before installation. De-energize and lock out any equipment before working on assemblies where this fastener is being replaced. Avoid cross-threading by starting the screw by hand and confirming thread engagement before applying torque.
