Martin Wrench Retainers are safe and easy-to-use tools designed to hold a striking wrench (also called a slugging wrench or hammer wrench) on a nut for a safer, hands-free one man operation.
The Wrench Retainer tool easily threads onto the stud. A spring loaded plate enables the wrench to be repositioned on the nut without removing the retainer.
Martin wrench retainers are sold individually and in sets. Industry Standard sizes are available in black oxide coated steel and suitable for use with Martin 6 pt and 12 pt Straight or Offset Wrenches.
