Value Collection 70020 Steel T-slot Bolt 7/8-9 Uncoated

Product Description

The VALUE COLLECTION 70020 is a steel T-slot bolt designed for securing workpieces and fixtures to machine tool tables, jigs, and other slotted clamping systems. It features a 7/8-9 UNC thread with a 2-inch thread length, a 1-inch slot width, and an uncoated finish. Manufactured from C-1045 grade steel with a Class 3 thread fit, this bolt delivers the mechanical strength required for production machining and fixture work. The head profile is sized to engage standard T-slots securely, preventing rotation during tightening. Machinists, toolmakers, and fixture builders are the primary installers in shop and industrial settings.

This T-slot bolt is suited for use with machine tool tables, milling fixtures, drill press tables, and workholding setups that use 1-inch T-slots. The 4-inch length under head accommodates standard clamping assemblies, and the 1-3/4-inch head width provides solid bearing surface within the slot. It is appropriate for both production and job-shop environments where repeatable, rigid workpiece location is required.

Key Features

• 7/8-9 UNC thread with Class 3 fit for precise thread engagement
• 2-inch thread length accommodates standard clamping nuts and straps
• 1-inch slot width fits standard machine table T-slots
• 4-inch length under head for use with typical clamping assemblies
• C-1045 grade steel construction for high tensile strength
• Uncoated finish suitable for direct use or field coating as needed

Compatibility

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

Installation Notes

Installation is typically performed by machinists or toolmakers using standard hand tools. Ensure the machine table or fixture is de-energized and stationary before inserting or adjusting T-slot hardware. Inspect the T-slot channel for burrs or debris before seating the bolt head to prevent galling or improper seating. Follow applicable shop safety procedures and equipment manufacturer guidelines for clamping torque and fixture load ratings.
