Injury free bolt tightening made easy

Page last modified
August 4 2023

The HYTORC Washer allows for more accurate, faster and safer bolt tightening as it simplifies the bolting set-up by removing the need for a reaction arm. This removes the well known pinching hazard and eliminates the risk of personal injury.

The HYTORC Washer can be used vertically and upside-down, with both ratchet links and socket wrenches and prevents galling and a damaged flange surface.

The use of HYTORC Washers is recommended by the ASME according to guidelines PCC-1-2013, VDI2230 and API.



Maximum safety: no more pinch hazards
Improved accuracy
No more shear, bending forces & no more galling
Equal bolt load: scatter in bolt load is cut in half
Durability: Relaxation & setting will decrease
In some cases you'll need longer bolts
