Value Collection 70028 Steel T-slot Bolt 7/8-9 Uncoated

Product Description

The VALUE COLLECTION 70028 is a steel T-slot bolt designed for use in T-slot fixtures, machine tables, jigs, and workholding setups common in machining and fabrication environments. It features a 7/8-9 UNC thread with a 2.5-inch thread length and is manufactured from C-1045 steel in an uncoated finish. The bolt measures 10 inches in length under the head, making it suitable for applications requiring deep slot engagement. The head is 1.75 inches wide and 0.625 inches tall, conforming to standard T-slot dimensions. Machinists, toolmakers, and fixture builders are the primary installers of this fastener.

This T-slot bolt is intended for use in milling machine tables, surface plates, modular fixturing systems, and similar industrial setups where components must be clamped securely into T-slots. The 1-inch slot width fits standard T-slot channels found on many machine tools and fixturing tables. Its Class 3 thread fit provides a close, accurate thread engagement appropriate for precision workholding applications. It is sold individually and is suited for both original equipment installations and replacement of worn or damaged hardware in existing fixtures.

Key Features

• 7/8-9 UNC thread with Class 3 fit for precise, secure thread engagement

• C-1045 steel construction provides good tensile strength for workholding loads
• Uncoated finish suitable for use as-is or for custom coating by the end user

Compatibility

Designed for use in standard 1-inch T-slot channels on milling machine tables, modular fixturing plates, and similar workholding equipment that accepts 7/8-9 T-slot hardware.

Installation Notes

T-slot bolts are typically installed by machinists or toolmakers during fixture setup or machine table clamping operations. Before installing or removing T-slot hardware, ensure the machine is de-energized and all moving components are fully stopped. Use appropriate wrenches or sockets sized for the 1.75-inch head width and verify thread engagement is sufficient before applying clamping force. Do not exceed the load rating of the fixture or machine table T-slot channel.
