10 Pieces Stainless Steel Hose Clamps with Worm Drive W4 V2A Clamping Range 12-22mm = 1,2-2,2cm Strip Width 9-mm Stainless Steel Hose Clip Hose Clamps Screw Clamps Band clamp DIN-3017

Worm-thread clamps with a metal strip made of stainless steel in 9 to 12 mm width.all.
parts of the clamp are made of stainless steel.Perforated metal bands are not loadable.Inferior hose clamps have metal bands with continuous perforation.Wherein the screw threads of the adjusting screw engage in each of the oblique-oval-oblong holes of the perforation.

-Since the perforation of the metal strip greatly reduces the mechanical strength of these hose clamps, we do not offer this supposedly favourable variant in our assortment.

from our range.Chrome tension rods are not suitableSome vendors save the stainless steel screw and use a cheaper,
chrome-plated set screw.This is not easy to recognise at first glance.Unfortunately,
contact corrosion repeatedly occurs in this context (according to DIN EN ISO 8044, this is
a corrosion due to the electrochemical reaction of two metallic materials or other
electron-conducting solids).In practice, the thread of the chrome-plated screw corrodes
at the point where it is in contact with the stainless steel strip.The pipe clamps dissolve, as the
thread is no longer positively connected to the clamp band.Water damages and
similar accidents are the result.If you are looking for a reliable hose clamp, make sure that
the metal band of the clamp is not perforated and that the entire hose clamp including
the clamping screw, is made of high quality stainless steel.With a magnet you can check yourself
whether the screw is made of stainless steel or not.If the screw is strongly magnetic,
then it is a galvanised iron screw.If the screw is not magnetic,
it is most likely stainless steel.
