Gibraltar MAS-0106 Hex Nut 2-5 Acme Thread 1018 Steel

Product Description

The GIBRALTAR MAS-0106 is a heavy-duty hex nut machined from Grade 1018 steel with a black oxide finish. It carries an Acme thread profile in a 2-5 thread size with a right-hand thread direction and a 2G thread fit class. The black oxide coating provides moderate corrosion resistance and reduces light reflection in service environments. At 2.5 inches across the flats and 0.5 inches in height, this nut is sized for large-diameter Acme threaded assemblies. It is installed by machinists, millwrights, and maintenance technicians working on power-transmission and linear-motion hardware.

This hex nut is intended for use in industrial and mechanical assemblies that use Acme-profile threaded rod or lead screw systems. Acme threads are common in power screws, jack screws, vises, press frames, and other linear-actuator mechanisms where the thread form must transmit significant axial load. The Grade 1018 steel construction provides adequate tensile strength for general mechanical service in these applications. Installation is typically performed in a shop or industrial maintenance setting.

Key Features

• Acme thread profile rated for axial load in power-transmission assemblies
• Grade 1018 steel construction balances machinability with tensile strength
• Black oxide finish reduces surface corrosion and minimizes light reflection
• Right-hand thread direction for standard tightening convention
• 2G thread fit class provides a close tolerance suitable for precision mechanical assemblies
• 2.5 inches across flats accommodates standard heavy-hex wrench tooling

Compatibility

Designed for use with Acme-profile threaded rod or lead screws in a 2-5 thread size with a 2G thread fit class. Verify thread profile, size, and fit class against the mating component before installation.

Installation Notes

Installation is typically performed by machinists or industrial maintenance technicians using a correctly sized open-end or box-end wrench sized for 2.5 inches across flats. De-energize and lock out any machinery before replacing or adjusting fasteners in a live assembly. Ensure the mating threaded rod or lead screw is clean and free of burrs before threading the nut. Do not apply excessive torque beyond the values specified in the equipment manufacturer documentation.
