Fel-Pro Loctite High Performance N-5000 High Purity Anti-Seize


Data from Oct. 1999

High Performance N-5000 is a specially formulated
nickel based anti-seize lubricant produced under 100%
controlled conditions for highest purity. High Performance N-
5000 is formulated with high purity raw materials and contains
only trace levels of halogens, sulfur, copper, aluminum and
heavy metals, including copper. It provides significant
improvement in anti-seize performance and gives it more
uniform torque tension. High Performance N-5000 has a
general composition of nickel and graphite flake in petroleum
carrier. All ingredients are selected for extreme purity.

Special Features:
· Superior anti-seize: extreme severity anti-seize tests show
stuck studs reduced by 90% compared to products
recommended for the same use
· More uniform torque tension: smaller difference in torque
coeffficients between bolting materials
· High purity: made from highest purity ingredents
· Free from copper: less than 25 ppm copper
· Typically used in applications with a dry surface
temperature of -29 to 1315ºC (-20 to 2400ºF)

· Bolts, studs, valves, pipe fittings, slip fits and press fits in
nuclear electric power generating plants, chemical plants,
pharmaceutical plants, paper mills and other locations
where stainless steel fasteners are used.
Operational Benefits:
· During assembly - prevents high friction, galling and
· Promotes uniform and predictable clamping.
· During operation - high purity prevents stress corrosion
· Disassembly - prevents seizing, galling, destruction of

· Before or during assembly, wipe brush onto threads and
other joint surfaces needing protection.
· Use full strength. Do not thin.

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
T = K x F x D
· T = Torque (in-lb, ft-lb, N-m)
· K = Torque coefficient or nut factor
· F = Clamp Load (lb, N)
· D = Nominal diameter of bolt (in, ft, m), determined

K Factor:
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, the manufacturer makes no warranty of specific performance
on any individual fastener. In critical applications, it is
necessary to determine K values independently.
