The WGC-MCS Series Mini worm gear clamp has a three piece construction featuring a 5/16" wide, 300 series stainless steel band and housing with a carbon steel 1/4" hex screw. The WGC-MSS Series version has the same construction, but uses a stainless steel screw. The three-piece streamlined housing design is ideal for tight installations. The arched, perforated slots offer added band strength and combine with the hex screw’s sharply defined hex angles for increased torque strength.
