Order LookupBox End Wrenches
Available2 products
Box-end wrenches have an enclosed head end that fits around and grips the entire head of the fastener. They provide more contact to the fastener than an open-end wrench and can apply more torque since the box end is less likely to slip off the fastener compared to an open-end wrench.
Head Size
SAE, 12-Point, Box End Leverage Wrenches
Box-end wrench leverage wrenches allow the attachment of an extension handle for hard-to-reach fasteners and provide additional torque to tighten fasteners more snugly. These single-end wrenches are SAE (inch) size for use on one specific size fastener. The enclosed head provides more contact to the fastener and allows more torque than an open-end wrench since the box end is less likely to slip off the fastener.

SAE, Single End, 12-Point, Nonsparking Box End Wrenches
These nonsparking box-end wrenches won’t spark during use and are suitable for use in flammable environments. They have an enclosed head on one end of the handle and provide a more secure grip on the full length of the handle compared to a double end box wrench. The single end is SAE (inch) size for use on one specific size fastener. Wrenches contain no iron, are nonmagnetic, and are suitable for use with magnetic resonance imaging (MRI) equipment. The enclosed head has more contact to the fastener and allows more torque than an open-end wrench since the box end is less likely to slip off the fastener.
