Value Collection 70030 Steel T-slot Bolt 7/8-9 Uncoated

Product Description

The VALUE COLLECTION 70030 is a heavy-duty steel T-slot bolt designed for secure clamping and fixturing applications on machine tables, milling machines, and other T-slotted workholding surfaces. Machined from C-1045 grade steel and left uncoated, this bolt fits a 1 inch slot width and provides a 3 inch thread length on a 7/8-9 UNC thread form. The Class 3 thread fit delivers a tight, reliable engagement suited to high-load setups. Weighing 3 pounds, this is a solid, full-size bolt intended for industrial and shop environments where workholding precision matters. Machinists, toolmakers, and maintenance technicians are the primary installers.

This T-slot bolt is used wherever T-slotted tables or fixtures require secure, adjustable clamping. Common applications include horizontal and vertical milling machines, surface grinders, drill press tables, and fabrication fixtures. The 14 inch length under head accommodates thick workpieces or stacked clamping setups. The 1-3/4 inch head width and 5/8 inch head height are sized to engage standard 1 inch T-slots without modification. It is well suited to both production shop environments and tool rooms requiring repeatable workholding.

Key Features

Compatibility

Designed for use in standard 1 inch T-slots on machine tables, milling fixtures, and similar industrial workholding equipment with 7/8-9 UNC threaded clamping hardware.

Installation Notes

T-slot bolts are typically installed by machinists or maintenance technicians during machine setup or fixture assembly. Before inserting or removing T-slot hardware, ensure the machine is powered down, the table is stationary, and all clamping loads are relieved. Use a properly sized wrench or socket on the mating nut — do not strike the bolt head to seat it in the slot. Inspect the slot and bolt head for burrs or debris before installation to maintain proper fit and prevent slot damage.
