Where this product is used

Ko-Ken Nut Twister and Bolt Twister sockets are engineered to grip and remove rounded, corroded, or damaged fasteners that conventional sockets can no longer engage.

• Recovery of damaged fasteners without drilling or fastener destruction where possible
• Fleet and workshop maintenance where fastener condition is variable and extraction is frequently required

Key specifications

Refer to the product title and description for specification details, or contact AIMS Industrial for full technical information on the Ko-ken 1/2" Nut Twister Socket Metric.

Selecting the right option

Select by drive size and the nominal fastener size — Nut Twister sockets engage fasteners up to 2mm smaller than nominal, as the fastener is expected to be partially rounded. These sockets are single-direction tools for extraction only; they will damage correctly sized fasteners if used for installation.
