KIRXST 3/4 inch Impact Hex Bit Socket Set (5-piece) for 14–24 mm Allen bits

If you regularly tackle mechanical repairs, you’ll know the annoying bit isn’t the job itself—it’s finding the right size quickly, and then keeping the socket seated when torque ramps up. This KIRXST 3/4 inch impact hex bit socket set is built for that sort of work: forged chrome molybdenum steel sockets, heat treated, with a black phosphate finish intended to resist corrosion. It’s a small set (five pieces), but the sizes cover a practical spread for common metric Allen fasteners.

Quick overview

This is a 3/4 inch drive impact hex bit socket set supplied as five metric sizes: H14, H17, H19, H22 and H24. It’s designed for automotive maintenance and mechanical repairs, with a natural fit for DIY tasks around the house. On paper, the main appeal is durability plus speed—hard-wearing material, and size markings that are meant to be easy to spot even in lower light.

The storage case is also part of the value. Instead of rummaging through loose bits and sockets, you get a straightforward way to keep everything together and portable, which matters if you’re working out of a garage cupboard or taking tools out to a job.

What it’s for (and what to expect)

The set is aimed at fastening work where an impact wrench (pneumatic or electric) is involved. The sockets use a precise hex bit structure intended to transfer torque securely and reduce the chance of slipping or rounding fasteners during higher-torque use.

A simple example: imagine you’re doing a brake/underbody check or a general mechanical adjustment and you need to remove a hex (Allen) style fastener. With this set, you can grab the closest matching size from the case, confirm it by the colour-coded markings, and then fit it to your impact tool without having to “try a few until it bites”.

Key materials and durability points

KIRXST states the sockets are forged from heat treated chrome molybdenum steel. That combination is often chosen for tools that see real stress rather than occasional use. The black phosphate finish is also meant to help with corrosion resistance.

It’s worth noting, though: a corrosion-resistant finish helps with day-to-day storage and workshop damp, but it won’t replace basic care. If tools sit wet or are exposed to salty conditions long-term, you still need to wipe down and store sensibly.

Size identification you’ll actually notice in use

Size recognition is where this set tries to save time. Each hexagon socket has high-contrast, colour coded markings so you can pick the right one quickly—even in low light.

In practice, this is the difference between “I’ll find the right socket” and “why is that one the wrong size?” When you’re mid-job, that little reduction in faff adds up.

Storage case and day-to-day practicality

The included plastic storage case supports organised storage and portability. For mechanics and DIY enthusiasts, keeping a compact set together is often more useful than people expect, especially if you don’t want a drawer full of mixed heads.

The case is also helpful when you’re transporting tools. It keeps the sockets from knocking around and makes it easier to grab the set and go.

Where it may fall short

Because it’s a five-piece set covering H14, H17, H19, H22 and H24, it won’t suit every Allen size you might come across. If your work regularly needs smaller or larger metric sizes outside that range, you may find yourself missing the one socket you need.

Also, while it’s described as compatible with pneumatic and electric impact wrenches, the set is still a specific tool format (impact hex bit sockets). If your jobs are mostly hand-driven or you prefer a broader assortment, you might want to compare with larger sets rather than rely on this narrow coverage.

Should you buy it?

It’s a sensible purchase if you want a compact 3/4 inch impact hex bit socket set for metric Allen fasteners in the H14–H24 range, particularly for automotive maintenance or routine mechanical repairs. The forged heat treated chrome molybdenum steel and phosphate finish are the sort of choices that fit professional-style expectations, and the colour coded size markings aim to reduce time lost on tool selection.

It may not be the best match if you frequently need Allen socket sizes outside H14, H17, H19, H22 and H24, or if you’re building a full workshop kit and prefer a more extensive assortment in one place. If you only need this type of socket occasionally, you might also decide whether a smaller or more general-purpose set would cover your needs with less commitment.
