Value Collection 70027 Steel T-slot Bolt 7/8-9 Uncoated

Product Description

The VALUE COLLECTION 70027 is a steel T-slot bolt designed for securing workpieces and fixtures to T-slotted machine tables, fixtures, and structural framing systems. It features a 7/8-9 UNC thread with a 2.5-inch thread length and fits a 1-inch slot width. The bolt is machined from C-1045 steel and left uncoated, making it suitable for general industrial and machining applications where a bare-steel finish is acceptable. The head dimensions — 1.75 inches wide and 0.625 inches tall — allow the bolt to seat properly within standard T-slots. Installation is performed by maintenance technicians and machinists working with milling machines, drill presses, surface plates, and modular fixturing systems.

This T-slot bolt is used in industrial and manufacturing environments where workholding, fixturing, or structural clamping is required. It is appropriate for use with standard 1-inch T-slot tables and compatible fixturing components. The 9-inch length under head accommodates setups with moderate stack height, such as riser blocks, step clamps, or multi-component fixtures. The Class 3 thread fit provides close tolerances suitable for precision fixturing work.

Key Features

• 7/8-9 UNC thread with 2.5-inch thread length for secure clamping engagement
• Fits 1-inch wide T-slots — compatible with standard machine table slot dimensions
• C-1045 steel construction provides solid strength for general industrial fixturing loads
• 9-inch length under head accommodates taller fixture stacks and riser setups
• Class 3 thread fit for close-tolerance, precision fixturing applications
• Uncoated finish — ready for use or field-applied corrosion protection as needed

Compatibility

Designed as a standard replacement or supplemental T-slot bolt for use with 1-inch T-slot machine tables, milling fixtures, and modular workholding systems that accept 7/8-9 UNC hardware.

Installation Notes

T-slot bolts are installed by machinists and maintenance personnel working on machine tools and fixturing setups. Always power down and lock out the machine before adjusting or installing workholding hardware. Insert the bolt head into the T-slot track before assembling the fixture stack, as the head cannot be inserted after components are in place. Tighten to the fixture or clamp manufacturer's recommended procedure using appropriate hand tools — do not over-torque, as this can damage the T-slot track or strip the thread.
