SM 9 W1 and W4 W1, W4, DIN 3017
SM 9 W1, W4 DIN 3017
The SM Clamp is capable of distributing radial forces with great efficiency and has a band which is smooth on both the inside and outside. It is used where safety is of prime importance and on relatively hard tubes, such as petrol and gas hoses etc.
The SM Clamp, also known as Nut-and-Bolt Clamp, often acts as a better seal on small diameter hoses than other hose clamps. The thin band fits around the hose precisely and as a result gives a high clamping force and a high pul! off resistance force.

The nut on the SM Clamp is captive and cannot be lost, which is a decisive safety advantage in engine maintenance for example.

The SM 9 Clamps are available as standard in W1 (aluzinc band) and W4 materials up to diameter 21 mm.

W1 version with combi cross head screw (7 mm), hex head with slot and cross.

W4 version with 7 mm hex head with cross.
