An anti-seize lubricant used on a bolt helps to develop greater clamp load for the same torque compared to an unlubricated bolt. An additional benefit is greater uniformity in clamp load among a series of bolts. The relationship between torque and clamp load is expressed in the following equation:
T = K x F x D
T = Torque (N·m, lb.in, lb.ft)
K = Torque coefficient or nut factor, determine experimentally
F = Clamp load (N, lb.)
D = Nominal diameter of bolt (mm, in.)
Torque coefficient, k:
12.7 mm steel bolts (grade 8) and nuts (grade 5) 0.16
12.7 mm steel bolts (grade 8) and nuts (grade 5), solvent cleaned, not lubricated 0.27
This product is not recommended for use in pure oxygen and/or oxygen rich systems and should not be selected as a lubricant for chlorine or other strong oxidizing materials. For safe handling information on this product, consult the Material Safety Data Sheet (MSDS).
Directions for use:
1. For best performance the mating surface should be clean and free of grease.
2. Note: When grinding or wire brushing, use a dust mask. Dust from cleaning threads may contain metal compounds. Inhalation may cause lung injury or other harm.
3. Apply thin coating to threads and flats of nuts and bolts, assemble.
