C5-A® Copper Based Anti-Seize
Exclusive formula suspends copper and graphite in a high quality grease. Protects metal parts from rust, corrosion, galling and seizing at temperatures to 1800°F.
Tested to MIL-PRF-907 rev E .
Product C5-A is a copper based anti-seize which
provides a shield against high temperature seizing and galling.
Studs, bolts, flanges, gaskets--all mated parts remove more
easily and in cleaner, better condition, in typical dry service
temperatures from -29 to +982ºC (-20 to +1800ºF). C5-A can
be used on copper, brass, cast iron, steel, all alloys including
stainless steel, all plastics and all non-metallic gasketing

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 (in-lb, ft-lb, N-m)
K = Torque coefficient or nut factor, determine experimentally.
F = Clamp Load (lb, N)
D = Nominal diameter of bolt (in, ft, m)
K factors are obtained on Grade 8, 1/2 steel bolts and Grade 5
nuts by a test procedure which measures torque tension
properties. Lubricant was applied to the bolt threads and both
faces of the washer. See properties chart for the torque
coefficient or K value for the anti-seize compounds. We feel
that this data fairly represents performance to be expected.
However, Loctite makes no warranty of specific performance
on any individual fastener. In critical applications, it is
necessary to determine K values independently.
