Mayhew Tools 16005 Low-Profile Dual Drive Set - Compact Metric Hex

In this review the Mayhew Tools 16005 Low-Profile Dual Drive Set is evaluated for anyone who needs compact, durable hex bits for tight spaces. The single biggest reason to buy is its low-profile, dual-drive design that lets the same stubby bit be driven by a 1/4-in square drive ratchet or by a 7/16-in wrench, making it especially useful when access is limited. The set's titanium nitride coating and S2 tool steel construction promise improved wear resistance and strength compared with standard bits.

Key Features

• Low-profile design: The 3/4-in length lets users reach fasteners in close quarters where standard drivers bind or won't fit.
• Dual Drive compatibility: Bits can be driven from the square drive end with a ratchet or from the outer diameter with a 7/16-in wrench for versatile use.
• Durable materials: Bits are made from S2 tool steel with a proprietary heat treat, giving better strength and resistance to chipping under heavy use.
• Titanium nitride coating: A titanium coating provides added wear resistance and helps slow surface corrosion in normal workshop conditions.
• Clear identification: Sockets are marked with their metric size and the set ships on a color coded storage rail for fast selection and organized storage.

Who It's For

The set is best for mechanics, maintenance techs, and hobbyists who frequently work in confined spaces or on assemblies where a full-length driver cannot fit. Its compact 3/4-in profile and dual-drive capability make it handy in toolboxes, service vans, and electronics or automotive work where access and torque direction need to change quickly.

Those who want a large, comprehensive metric multi-tool with extensions or deep sockets should look elsewhere, since this set focuses on stubby, accessible bits rather than long reach or specialty drives. If corrosion resistance under wet conditions is an absolute requirement, consider storing these bits dry and checking finish expectations since some users still report rust in adverse conditions.

Pros & Cons

Pros

• Low-profile, 3/4-in length provides access in tight quarters where standard drivers cannot reach.
• Dual Drive design adds flexibility by working with a 1/4-in square drive ratchet or a 7/16-in wrench.
• Proprietary heat-treated S2 steel construction and titanium nitride coating improve strength and wear resistance.
• Color coded storage rail and marked sizes speed identification and organization.

Cons

• Titanium coating improves wear resistance but a few users report corrosion over time, so storage and moisture exposure matter.

Frequently Asked Questions

Can these bits be used with a standard 1/4-in ratchet?
Yes, the dual-drive bits accept a 1/4-in square drive for use with ratchets, socket spinners, or T-handles.

What metric sizes are included?
The set includes 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 10mm, 12mm, and 13mm bits.

Is the coating corrosion proof?
The titanium nitride coating increases wear resistance and slows corrosion, but users should store bits dry and inspect them if used in wet or corrosive environments.
