General-Purpose Anti-Seize Compound

This copper-based paste prevents seizing and galling on threaded fasteners in automotive and industrial maintenance. The brush-top can delivers controlled application for mechanics and technicians who need reliable thread lubrication during assembly. It is formulated to withstand extreme temperatures from -30 °F to 800 °F. The non-flammable composition adds safety in workshop environments.

Suited for high-heat thread protection.

Mechanics assembling exhaust manifolds, brake calipers or spark plugs benefit from the copper formula's heat resistance and corrosion barrier. The 2 oz container covers routine maintenance tasks on passenger and light commercial vehicles. Buyers who require a low-friction lubricant for sliding surfaces or a food-grade compound for sanitary equipment should select a different product type.

Two-ounce brush-top covers dozens of fasteners

The paste volume handles repeated disassembly and reassembly of typical bolt patterns found in brake, exhaust and suspension work. Copper particles maintain lubricity up to the rated 800 °F limit, preventing corrosion seizure during thermal cycling. Very large industrial flanges or continuous high-volume production lines will exhaust the can quickly and require a larger package.

Questions about this item

What thread size or fastener type do I need to have on hand before applying the 2 oz copper paste from the brush-top can?

The compound is a general-purpose copper paste rated from -30 °F to 800 °F, so it works on most steel, stainless or plated threads you already plan to assemble.

Will the 21002 compound damage the factory finish on older plated bolts I want to reuse?

The non-flammable copper formula is chemically inert toward common zinc, cadmium and chrome platings found on older hardware.

How can I confirm the paste is still effective after I brush it onto the threads?

A consistent copper-coloured film covering every thread flank indicates full coverage; the product remains stable up to its 800 °F rating.
