DIYUK Worm Drive Hose Clamps DIN 3017, W2 Stainless Steel Adjustable Pipe Clips 190-210mm, Pack of 5

Weather resistant, long lasting build: the band and housing are AISI 430 stainless steel for strong resistance to rust and general weathering, paired with a zinc-plated carbon steel screw that holds torque more reliably under repeated tightening than a stainless screw would. Fits hoses from 190mm to 210mm: this 190-210mm clamp closes down to 190mm and opens as wide as 210mm, so measure the hose once it is fitted over its connector (not the hose alone) and pick a size that closes comfortably within its range, with the screw still short of the end of its travel. Suited to large-bore hose and ducting: at the top of the size range, this clamp is intended for general workshop and light industrial hose and pipe fastening on larger-bore hose and ducting, as well as HVAC and ducting connections onto spigots and connectors. Supplied as a pack of 5: five 190-210mm W2 worm drive clamps in a single pack, enough to secure multiple large-bore hose or ducting connections from one order. Manufactured to DIN 3017: the recognised European standard governing the dimensions and construction of worm drive hose clamps, with a slotted screw head that takes a flat-blade or Phillips driver and a recommended tightening torque of 4.0 Nm (approx. 35 lbf.in) to guide correct fitting without overtightening.
