Mitee-bite 90125 Irregular Hex Clamp 7-12mm 1/2-13 Stud

Product Description

The MITEE-BITE 90125 is an irregular hex clamp designed for securing workpieces during machining operations where standard hex clamps cannot be used. It engages hex-profile stock ranging from 7 to 12 millimeters and uses a 1/2-13 stud thread for mounting to a fixture plate or T-slot table. The serrated edge contact surface increases grip, generating up to 4,000 pounds of holding force when the stud is torqued to 65 foot-pounds. The hex height measures 0.394 inches (10 millimeters), keeping a low profile over the workpiece. This clamp is installed by machinists and toolmakers in milling, grinding, and precision fixturing applications.

The 90125 is suited for production and jobshop environments where irregular hex bar stock or hex-profile workpieces must be held securely without distortion. Its compact hex height makes it practical in setups where clearance is limited and the spindle or grinding wheel must pass close to the clamping hardware. A single clamp ships per package, allowing incremental fixture builds or direct replacement of a worn or damaged unit.

Key Features

• Accommodates hex stock from 7 to 12 millimeters — one clamp covers a range of hex sizes
• Serrated edge contact surface maximizes grip and resists workpiece movement under cutting forces
• 4,000 pound holding force at rated torque provides reliable clamping for milling and grinding
• Low 0.394-inch hex height reduces interference with toolpaths and fixturing clearance
• 1/2-13 stud thread is a common machine-tool standard, compatible with most T-slot hardware
• 1-inch thread length gives adequate stud engagement for secure mounting

Compatibility

Designed for use with hex-profile workpieces measuring 7 to 12 millimeters across flats, mounted via standard 1/2-13 stud thread into fixture plates, tombstones, or T-slot tables used in milling and grinding setups.

Installation Notes

Installation is performed by machinists or toolmakers. Power down and lock out the machine before adjusting or repositioning clamps. Thread the 1/2-13 stud into a properly tapped fixture hole or T-nut, seat the clamp against the hex workpiece, and torque to 65 foot-pounds using a calibrated torque wrench. Inspect the serrated contact surface for wear before reuse, as a damaged edge reduces holding force.
