Value Collection 60020 T-slot Bolt 7/8-9 Steel Uncoated

Product Description

The VALUE COLLECTION 60020 is a steel T-slot bolt designed for securing workpieces and fixtures to T-slotted tables, machine tool beds, and fixture plates commonly found in machining, fabrication, and industrial setups. The bolt features a 7/8-9 UNC thread with a 2-inch thread length and a head sized to fit a 7/8-inch slot width. Made from C-1045 steel in an uncoated finish, it provides solid mechanical strength for clamping applications. The head dimensions — 1.5 inches wide and 9/16 inches tall — allow the bolt to slide into standard T-slots and lock into position under load. Installation is typically performed by machinists, toolroom technicians, and maintenance trades.

This T-slot bolt is suited for use on milling machine tables, surface plates, welding fixtures, and other workholding setups that use standard T-slot channels. The 4-inch length under the head provides clearance for a range of fixture thicknesses and clamping configurations. The Class 3 thread fit ensures a controlled, close-tolerance engagement with standard hex nuts or T-slot nuts used in workholding assemblies. It is sold individually, making it practical for replacement or small-quantity toolroom restocking.

Key Features

• 7/8-9 UNC thread with 2-inch thread length for standard workholding nut engagement
• Head sized at 1.5 inches wide and 9/16 inches tall to fit 7/8-inch T-slots
• 4-inch length under the head accommodates varied fixture and clamping plate thicknesses
• C-1045 steel construction provides reliable tensile and shear strength for clamping loads
• Class 3 thread fit for close-tolerance, secure mating with T-slot nuts
• Uncoated finish — suitable for dry or lightly lubricated toolroom environments

Compatibility

Designed for use in standard 7/8-inch T-slots on machine tool tables, fixture plates, and workholding systems that accept 7/8-9 UNC T-slot fasteners.

Installation Notes

Installation is typically performed by machinists or maintenance technicians as part of workholding or fixture setup. Before installing or removing T-slot bolts, ensure the machine table is de-energized and any moving axes are locked or at rest. Slide the bolt head into the T-slot channel from an open end or through a cross slot, then align and thread the nut by hand before tightening with a wrench. Do not overtighten beyond the fastener grade rating, and inspect the slot for burrs or debris that could prevent full seating of the bolt head.
