3/8"SD Britool England Fixed Extension Bars 75mm - 450mm

These Britool Hallmark 3/8" square drive extension bars are manufactured from high-quality alloy steel and were produced in the original Britool UK manufacturing plant prior to its closure, making them increasingly rare and highly sought after.

Each extension bar features precision-machined square drive ends with ball retaining grooves on each face, ensuring a secure and positive fit with all 3/8" drive sockets and accessories. Designed for strength, durability, and consistent torque transfer, they are ideal for professional automotive, mechanical, and general workshop use.

Due to their UK manufacture and discontinued status, stock availability is limited. The extension bars are available individually in multiple lengths or can be purchased together as a convenient four-piece set.

Available lengths include 75mm, 100mm, 250mm, 300mm, and 450mm. Also available as a 4-piece set under part reference MESET4.

Please note pictures used are to show overall look and design of the bars and maybe of a different size but you will receive the size as per your order.
