DIN 3017 Worm-Drive Hose Clamp

The clamps are made of stainless steel. The design uses the principle of a spacer-type lock joint in the band, which prevents its deformation under high tightening forces. The band is well-flanged, without slots, and does not damage the connected pipes. The screw (7 mm) turns smoothly without effort. Band width is 9 and 12 mm. W2 — the clamp is made of stainless, slightly magnetic steel.
