Value Collection 40023 T-slot Bolt 3/4-10 Steel Uncoated

Product Description

The VALUE COLLECTION 40023 is a steel T-slot bolt designed for securing workpieces, fixtures, and tooling to T-slotted machine tables, milling machine beds, and similar industrial fixturing surfaces. Manufactured from C-1045 grade steel in an uncoated finish, this bolt features a 3/4-10 UNC thread with a 2-inch thread length and is built to a Class 3 thread fit for precise, reliable engagement. The head geometry is sized for a 3/4-inch slot width, a 1-1/4-inch head width, and a 7/16-inch head height, with an overall length under head of 5-1/2 inches. Installation is handled by machinists, toolmakers, and fixturing technicians in manufacturing and machine shop environments.

This T-slot bolt is suited for use with standard inch-series T-slot tables found on vertical milling machines, horizontal mills, surface grinders, and modular fixturing systems that accept 3/4-inch T-slots. The 3/4-10 UNC thread size makes it compatible with standard hex nuts, T-nuts, and stud hardware used in conventional workholding setups. At 0.92 pounds, it provides the mass and rigidity appropriate for medium-to-heavy duty clamping applications in production and job-shop settings.

Key Features

• 3/4-10 UNC thread with Class 3 fit for accurate, repeatable engagement
• 2-inch thread length accommodates standard T-nuts and clamping hardware
• Head sized for 3/4-inch T-slots with 1-1/4-inch head width and 7/16-inch head height
• 5-1/2-inch length under head provides clearance for thick fixtures and workpieces
• C-1045 grade steel construction for strength in industrial fixturing duty
• Uncoated finish — suitable for shop environments where corrosion protection is handled separately

Compatibility

Designed for use in standard inch-series 3/4-inch T-slot machine tables, including those found on milling machines, surface grinders, and modular fixturing systems that accept 3/4-10 UNC T-slot hardware.

Installation Notes

T-slot bolts are installed by machinists and toolmakers as part of workholding and fixturing setups. Before installing or removing fixturing hardware, ensure the machine is powered down, locked out, and tagged out per applicable OSHA lockout/tagout procedures. Insert the bolt head into the T-slot channel before engaging the nut — the head cannot be inserted from the end of the slot under load. Use calibrated torque tooling and follow the fixture manufacturer's clamping force recommendations; do not over-torque, as this can damage the T-slot table or deform the bolt head.
