Overview
WELD ON WRENCH HEXES Product Overview
1865-101 is a mild steel weld-on wrench hex for 3/8″ OD tubing. Wrench size: 5/8″ across flats. Tubing ID clearance: 0.39″ nominal.
Weld-on wrench hexes are slid over a tube and tack-welded at the mid-point to provide a hex gripping surface for a wrench — allowing the tube to be held or turned without marring the surface. Used to add a turn-point on chromoly push rods, adjustable links, and steering tubes where a threaded hex body is not already present. Mild steel construction; compatible with most standard tubing ODs.
Fits 3/8″ OD tubing. Pairs with CMT chromoly tubing and WTF tube adapters. All standard tubing sizes from 3/8″ to 2″ OD available across the 1865 series.
