toolant TA01001001 Impact Allen Wrench Bit Set, 20-Piece Metric & SAE

Magnetic tips help hold screws during installation, while engraved size markings make it easier to choose the right bit for the fastener.

The toolant TA01001001 set pairs 20 impact-ready hex bits with four mini L-shaped hex keys for manual work on small fasteners.

Metric and SAE sizes are organized in labeled holders inside a storage case, keeping the set together for workshop tasks and household projects.

How it fits

The 2-inch bits have standard 1/4-inch hex shanks for compatible impact drivers, drills, and manual screwdrivers. They’re designed for internal-hex fasteners, making them useful for automotive maintenance, motorcycle and engine work, dashboard tasks, furniture assembly, and general DIY. For example, a compatible driver can handle repeated hex fasteners during furniture assembly, while the mini L-shaped keys provide a manual option for smaller fasteners.

The set covers both measurement systems: 10 SAE bits range from 5/64" to 5/16", and 10 metric bits range from 1.5 to 8 mm. Engraved markings and separate labeled Metric and SAE holders help identify and return each size. Compared with assembling a collection of loose hex keys, this set combines driver-ready bits and compact manual keys in one organized case.

Benefits

S2 alloy steel bodies and CNC-machined tips are made for consistent engagement with hex fasteners. A torsion zone helps absorb peak torque during impact driving, and the manganese phosphate finish helps resist rust. Magnetic tips can help pick up and hold screws as they’re positioned, which is especially useful when working with a driver in confined spaces.

The four included L-shaped keys add manual access to 1.27, 1.5, 2, and 2.5 mm fasteners. This gives the set a useful mix of powered driving and hand operation without relying on one format for every task.

Buyers often appreciate the selection of metric and SAE sizes, the markings, and the convenience of using the bits with drivers. Feedback on durability is mixed: some report that the bits hold up well, while others describe snapping or stripping during use. These experiences are individual reports, not a durability guarantee.
