    • Clamps - Worm Drive

    Our Norma brand worm drive clamps are Made in Germany and are all W4 which means they are all 304 stainless steel, yes, it is all 304 stainless steel so you know that they are excellent quality.   I often tighten the clamps using a ring spanner and I have not stripped one yet.  Excellent value as they will last for many years without failing.
