Description Set of HEX L-keys 13 pcs. (1/16-3/4") JCB Tools JCB-5137S

A professional solution for servicing American and British equipment with uncompromising JCB reliability.

Faced with inch fasteners where metric wrenches are powerless? The JCB-5137S set is a professional SAE standard set designed for the toughest operating conditions. It contains 13 L-shaped wrenches, including rare power sizes up to 3/4", which allows you to work with massive components of industrial equipment and special machinery. Made of premium chrome-vanadium steel (Cr-V), these wrenches have a huge margin of safety. They do not bend or "lick" the edges even at extreme torques. This is a tool that is bought once and serves for decades in car services, production facilities, and the agricultural sector.

Why do craftsmen choose this set?

Cr-V power steel
High-alloy chrome-vanadium steel has undergone special heat treatment, which guarantees resistance to chipping and deformation under load.

Giant sizes (up to 3/4")
Unlike cheap analogues, the set contains massive 1/2", 9/16", 5/8" and 3/4" wrenches for working with heavy bolts.

HEX Precision Fit
Precision milling of the edges ensures the tightest fit to the fastener, eliminating the risk of damage to the slot.

Anti-corrosion coating
The proprietary finish protects the metal from moisture, lubricants, and aggressive technical fluids common in repair areas.

Reinforced lever
The L-shaped form allows you to effectively use the long part as a lever for breaking off seized connections.

Heavy Duty Organizer
A reliable holder with clear markings for each wrench allows you to instantly find the right size and maintain order.

Safety rules

• Always use a wrench that exactly matches the size of the fastener. Using metric wrenches on inch bolts will destroy the edges.
• Clean the screw head slot of dirt before work to ensure full immersion of the wrench.
• Do not use hammers or extensions to increase the leverage — the tool is designed for manual effort.
• After working in aggressive environments, wipe the wrenches with a dry cloth.
