Gibraltar 20608G 38-piece T-nut Stud Kit 5/8-11 Stud

Product Description

The GIBRALTAR 20608G is a 38-piece T-nut stud kit designed for securing workpieces and fixtures to T-slot machine tables, milling machines, and similar workholding setups. The kit uses a 5/8-11 stud thread and fits T-slots measuring 11/16 inches wide, with a T-slot nut width of 1-1/8 inches. Stud lengths range from 3 inches through 8 inches, giving machinists and toolroom technicians the flexibility to accommodate varying workpiece heights and clamping configurations without sourcing individual components. The full kit weighs 13 pounds.

This kit is suited for machine shop environments where T-slot workholding is standard. Typical applications include vertical and horizontal milling operations, surface grinding setups, and fixture building on cast-iron T-slot tables. The six included stud lengths — 3, 4, 5, 6, 7, and 8 inches — cover a broad range of clamping heights, making this kit practical for general-purpose toolroom stock or dedicated workholding stations.

Key Features

• 38-piece kit with six stud lengths: 3, 4, 5, 6, 7, and 8 inches
• 5/8-11 stud thread size for standard milling table compatibility
• 11/16 inch T-slot width fits common machine table T-slots
• T-slot nut width of 1-1/8 inches for positive engagement in the slot

Compatibility

Designed for use with T-slot machine tables that accept a 5/8-11 stud thread and an 11/16 inch T-slot width with a 1-1/8 inch nut width.

Installation Notes

Installation is typically performed by machinists or toolroom technicians familiar with T-slot workholding practices. Always ensure the machine table and T-slots are clean and free of chips or debris before inserting T-nuts. Tighten studs and clamping hardware evenly to prevent workpiece movement during operation. Follow the machine manufacturer and applicable shop safety guidelines when setting up workholding systems.
