â?¢ Always use wrench sizes which fit the fastener. Do not use metric wrenches on SAE fasteners, or vice versa.
â?¢ Always pull the tools toward you. Do not push.
â?¢ Always use box-end as a primary choice and open-end as secondary where possible. Box-end secures the fastener better which help prevent slipping when using a wrench.
â?¢ Always ensure the wrench is securely fitted on the fastener and the adjustable wrench is adjusted to grip the fastener firmly before fastening.
â?¢ Do not use wrenches that are bent, cracked or badly worn.
â?¢ Do not overload a wrench by using pipes or other extensions to increase leverage or by striking with a hammer to gain extra strength. Doing so exposes sudden breakage and can result in bodily injury. Wrenches with extra-long or striking-face are designed for these purposes.
â?¢ Do not use a wrench if the fastener requires a specific torque. Instead, use a torque wrench to avoid under or over torquing.
