Apex 81640 Stubby Combination Wrench 12 Point 16MM

Product Description

The APEX 81640 is a stubby combination wrench designed for work in tight spaces where a standard-length wrench cannot reach or swing freely. Built from alloy steel, it features a 12-point box end offset at 15 degrees to improve access to recessed fasteners. The off-corner loading design on both ends delivers a stronger grip on fastener flats, reduces the risk of rounding fastener heads, and transfers up to 25% more torque compared to standard corner-loading designs. The size is stamped directly into the beam for permanent identification without labels or stickers. This wrench is sized at 16MM and is well-suited for automotive, mechanical, and light industrial service work.

The 81640 fits into a stubby form factor measuring 4.862 inches in overall length, making it practical for confined fastener locations such as engine bays, equipment panels, and tight mechanical assemblies. The 12-point box end provides multiple engagement positions, reducing the arc needed between strokes. The open end provides quick fastener contact for rapid turning in accessible locations. This wrench is typically used by automotive technicians, millwrights, and general maintenance professionals who require a compact wrench in metric sizing.

Key Features

Compatibility

Designed as a standard 16MM stubby combination wrench for use with metric fasteners in automotive, mechanical, and general maintenance applications.

Installation Notes

This wrench is a hand tool requiring no installation. Always ensure the correct metric size is matched to the fastener before applying torque to avoid rounding. Use in the box-end orientation when higher torque is needed or when fastener access is limited. Inspect the wrench for cracks or deformation before each use and do not use extension bars or pipes to increase leverage on a stubby wrench.
