FAQ
Can I use this lube on stainless steel bolts?
Yes, the zinc‑based formulation is safe for stainless steel and helps prevent galling while maintaining corrosion resistance.
Is this product suitable for high‑temperature engine assembly?
Absolutely. The semi‑synthetic base performs well up to 200 °C, making it ideal for engine and transmission assembly.
How much lube should I apply to a typical bolt?
A thin, even coat covering the threads is sufficient. Over‑application can attract debris and affect torque accuracy.
Does the lube affect torque specifications?
When applied correctly, it reduces friction, allowing you to achieve the intended torque value more reliably.
Can I store the lube for long periods?
Yes, store in a cool, dry place. The product remains effective for several years if the seal remains intact.
