Oetiker Type 177 - W4 12 mm Worm Drive Clamps conform to DIN 3017

 

Clamp design

Oetiker Worm Drive Clamps are technically advanced, multi-range hose clamps, which cover a very wide range of clamping diameters. Hoses of differing diameters can be securely connected with a single size. Manufactured by cold-forming, the bands of these worm drive clamps have a slightly curved form. The depth of the thread impressions reduces to each side – the thread impressions have their full depth in the middle. Worm drive clamps in material quality W2 have a 7 A/F hexagonhead screw with cross recess (Phillips). Clamps in material quality W4 have a hexagon-head screw (7 A/F) with a standard screwdriver slot.

Recommended assembly
For professional assembly, we recommend using a flexible screwdriver. This tool ensures safe assembly even in hard-toreach locations. For series assembly requiring high process reliability, electronically monitored Oetiker controlled-torque screwdrivers should be used.

 

Certificates and documentation are available for these products. If desired, you can order these together with your order.

 

We can offer:

• Certificate of Conformity (CoC)
• EN 10204 3.1 Inspection Certificate

 

Certificates must be requested at the time of ordering. Certificates requested after shipment may incur additional administrative costs and cannot always be provided retrospectively.

You will find the certificates at the bottom of the drop-down order menu at the top right of this page.

 

Generally, a subsequent order is significantly more expensive due to the administrative burden.
