ND LM-1293®

Overview

ND LM-1293 is an automotive approved process in which fasteners are accurately coated with one of a variety of thread masking and lubricating materials. The use of a PTFE material and a proprietary binder system in ND LM-1293 makes it the ideal coating for many applications.

How it Works

ND LM-1293 can be applied to male or female, ferrous or non-ferrous threaded fasteners of virtually any finish. It is a cross-linked coating providing excellent solvent, high temperature, e-coat,and weld spatter resistance, with an improvement to torque-tension properties. ND LM-1293 lubricates fastener threads to reduce driving friction, heat buildup, and thread galling in long rundowns while helping to ensure uniform clamp loading.

Features

Reliable Masking

ND LM-1293 prevents undesirable substances such as electro-deposited undercoatings, weld spatter and some other materials from adhering to fastener threads.

Low Heat Process

Unlike competitive processes which often subject parts to extremely high temperatures that may damage or discolor the fastener, ND's unique patented process employs minimal heat.

Minimal Pre-cleaning

Unlike competitive processes that require parts be completely free of oil or other rust preventative coatings, only parts with excess oil or surface contaminants may require pre-cleaning.

Eliminates Capping & Plugging

ND LM-1293 eliminates the need to cap male and plug female threads.

Increases Productivity

By providing additional lubricity, ND LM-1293 speeds assembly operations and increases productivity.

Versatile Application

ND LM-1293 can be applied to both threaded, male or female, and non-threaded fasteners.

Benefits

  • Saves Time & Money: Fasteners coated with ND LM-1293 eliminate the need for re-tapping, plugging, capping, and slave bolts. This increases greatly reduces labor and material costs.
  • Quality Control: Pre-Applied ND LM-1293 fasteners are coated to specification, ensuring consistent performance.
  • Improved Consistency: ND LM-1293 acts as a lubricant and reduces variation in torque tension while lowering installation torque.
  • Electrical Grounding: ND LM-1293 helps to guarantee a good electrical ground.

Notes

  • Indefinite on part life under ideal storage conditions [+40°F (+4°C) to +90°F (+32°C)], but re-certification must occur once a year.
  • To meet your specific application needs, ND LM-1293 employs a wide range of polymers, including fluorinated ethylene polymer material.
  • As with all our Pre-Applied products, ND Industries can apply ND LM-1293 to your fasteners at any one of our regional service centers, or we can supply you with completed pre-applied fasteners.
