Avoid finger injuries and trapped hands with the hands free 'Backing Tool'

The 'hands free' Backing Tool is safer than traditional methods of bracing the nut in flange bolting, minimising the risk of trapped hands and fingers. The Backing Tool needs only one person to torque/de-torque the fastener and arrest the bolt head, unlike the need for two people when using a flogger for the same purpose. Backing Tool features and benefits include:

  • Profiled to ensure full nut engagement at the flange weld neck;
  • Spring loaded adjustable retaining ball to hold the Backing Tool onto the nut giving best fit (needs to be adjusted only once);
  • Single cast construction for strength;
  • A bi-hexagon / 12 point design for easy locating on the nut;
  • Fixing ring for the attachment of a lanyard to prevent the Backing Tool from falling;
  • Easily released without altering the tension in the bolt;
  • Highly portable - suitable for use on large or remote sites.

Oil refineries, chemical plants, power generation plants, the utility sector, offshore oil and gas industries are just some of the areas that can benefit from using the Backing Tool.

Backing Tools are available in Imperial sizes 7/8" A/F (1/2" UNC) to 5-3/8" A/F (3-1/2" UNC) to correspond with UNC flange bolt sizes. They are also offered in a choice of kits.
