Common Questions about Anti-Seize Compounds
What is anti-seize compound used for?
Anti-seize compound is a high-temperature lubricating paste applied to threaded fasteners and contact surfaces to prevent galling, seizing and corrosion bonding. Applied to bolt threads before assembly, it keeps the joint serviceable — bolts come loose cleanly months or years later instead of snapping off or rounding out under removal.
When should I use anti-seize?
Use anti-seize on threaded fasteners exposed to heat, corrosion or dissimilar metal contact — exhaust fasteners, brake hardware, stainless threads, aluminium-to-steel joints, machine spindles and marine fittings. Do not use on torque-critical fasteners unless torque values are adjusted for the lubricant friction effect — lubrication changes the torque-to-tension relationship.
What is the difference between copper, nickel and aluminium anti-seize?
Copper-based anti-seize handles general workshop temperature — the most common variant. Nickel-based handles higher heat — used on exhaust and high-temperature joints. Aluminium-based is general-purpose and stainless-compatible. Food-grade and graphite-based variants exist for specialised applications. AIMS stocks Loctite, CRC and Permatex anti-seize variants across the workshop range.
Can I use anti-seize on stainless steel?
Yes — stainless threads gall, or cold-weld, under load, making fastener removal very difficult. A nickel or copper-free anti-seize on stainless threads breaks the metal-to-metal contact that causes galling. Many workshop stainless installations specify anti-seize as standard practice, especially on larger diameters and high-clamp-load fasteners.
Does anti-seize affect bolt torque?
Yes — anti-seize reduces friction, so for any given torque setting, more clamp force is applied to the joint. Manufacturer-specified dry torque values can over-stress a lubricated bolt. Where torque is critical, reduce target torque to account for lubrication, or follow the fastener manufacturer lubricated-torque specification on the data sheet.
Anti-Seize Compound Quick Reference — By Type & Temperature
Anti-seize compounds prevent galling, seizure and corrosion-bonding of threaded fasteners and metal-to-metal joints — ensuring dismantling remains possible after high-temp service or long exposure. The compound type sets the maximum service temperature and the assembly environment (electrical conductivity, food contact, marine corrosion). AIMS stocks Loctite, CRC, Rocol, Molytec, Devcon and Molybond.
| Compound Type | Max Service Temp | Conductivity | Best For |
|---|---|---|---|
| Copper-Based | 1100 °C | Conductive | Exhaust system fasteners, high-temp flanges, brake hardware |
| Nickel-Based | 1425 °C | Conductive | Stainless steel assemblies (prevents galling), pressure vessel studs, valve stems |
| Aluminium-Based | 900 °C | Conductive | General-purpose high-temp, replacement for copper where required |
| Silver / Graphite | 1100 °C | Conductive | Specialty high-temp, oxygen service (lead-free), exotic alloys |
| Moly / Synthetic Grease | 400 °C | Non-conductive (oil-based) | General mechanical assembly, lower-temp fasteners, electrical-isolation applications |
| Food-Grade (NSF H1) | 200-260 °C | Non-conductive | Food processing, pharmaceutical, beverage equipment fasteners |
| Marine / Salt-Water | 250-400 °C | Varies | Coastal, offshore, propeller shaft hardware, deck fittings |
For application technique and torque reduction guidance, see our anti-seize compound guide. NOTE: anti-seize lowers the friction coefficient at threads — reduce specified dry torque by ~20% to avoid over-tightening. For thread sealing (not anti-seize), see thread sealants.

Selection & Application Guide
- Torque Reduction Factor: Anti-seize compounds reduce the torque required to achieve a given bolt preload. If the joint specifies dry torque values, reduce applied torque by approximately 20–30% when using anti-seize — or follow the compound manufacturer's published nut factor (K) for the specific product.
- Anti-Seize Is Not a Thread Sealant: Anti-seize does not seal threads against fluid or gas leakage. Use PTFE tape, liquid thread sealant, or anaerobic thread sealant where pressure sealing is required.
- Application Method: Apply a thin, even coat to the first few threads and bearing surfaces only. Excess compound can hydraulically lock assemblies or contaminate adjacent components. Brush or spatula application is preferred for control and consistency.
