Jergens 43312 Blind Tapped T-slot Nut 3/4-10 Steel

Product Description

The JERGENS 43312 is a blind tapped T-slot nut designed for use with 3/4-10 threaded fasteners in standard T-slot fixturing applications. Manufactured from C-1018 steel with a black oxide finish, this nut fits a 0.875 inch slot width and provides a solid, vibration-resistant anchor point for workholding setups. The base measures 1.5 inches wide by 0.5625 inches tall, and the overall length and height are 1.5 inches and 1 inch respectively. The blind tap design prevents chips and coolant from entering the threaded bore, keeping threads clean in production environments. This nut is a right-hand thread configuration and is sold individually.

This T-slot nut is used in machine tool fixturing, jig and fixture building, and workholding on milling machines, drilling tables, and other equipment with standard T-slot tables. It is suited for both production shop environments and toolroom applications where a reliable, repeatable clamping anchor is required. Machinists, toolmakers, and fixture builders install this component as part of modular workholding systems.

Key Features

• Blind tapped bore keeps threads free of chips, coolant, and debris
• 3/4-10 right-hand thread for compatibility with standard clamping studs and bolts
• C-1018 steel construction provides reliable strength for fixturing loads
• Black oxide finish offers mild corrosion resistance and reduces light reflection in shop environments
• Precise 0.875 inch slot width fit for consistent seating in standard T-slots
• Compact 1.5 inch overall length suits tight fixture layouts

Compatibility

Designed as an OEM-style replacement or direct-install component for standard T-slot tables and fixturing systems using a 7/8 inch slot width and 3/4-10 threaded clamping hardware.

Installation Notes

Installation is performed by machinists or toolmakers during fixture assembly or workholding setup. The nut slides into the T-slot from the end of the table or through a slot opening, then is oriented and positioned before the mating stud or bolt is threaded in by hand and torqued according to the fixture design requirements. Always verify slot width and thread size match before assembly to avoid cross-threading or improper seating.
