I bid you welcome to an exciting follow-up to a late-January post: Stubby bits for low-profile offset ratcheting screwdrivers. A few months back, I got a couple of low-profile, offset, ratcheting screwdrivers for a specific little project. For my project, I wanted to use Torx-drive fasteners, but the short bits included with the screwdrivers didn’t include any Torx bits, and my existing bit sets were long-ish (25mm from end to end), too long for the low-profile screwdrivers to be sufficiently low-profile for my purposes.

The bits included with the screwdrivers are 16mm long:

Each of the low-profile screwdrivers came with the same small bit assortment: 3 Phillips-head bits, 2 flat-head bits, and 3 hex-head bits. All are 16mm long.

I hunted around on Taobao and found cheap sets of 18mm-long bits, including a 3-piece Torx bit set. I bought one of those for about US $3.75. There was also a large set from a company with an unfamiliar name (JTX Auto Tools): [JTC-7801] 78 PCS DOUBLE END MINI RATCHET BIT SET. The company is based in Georgia and the sticker on the plastic case says the contents were manufactured in Taiwan. The price on the JTC site is currently $120.38 (supposedly marked down from $126.72) and I paid about 3/4 of the discounted price at jcautotools.com.

The bits in the top two rows of the set are 22mm long and have 10mm hex shanks. The bottom three rows contain 18mm-long, 1/4″ (6.35mm) hex-shank bits, which fit the little ratcheting screwdrivers I’d bought previously.

Measured the length of one of the 6.35mm-shank bits in the JTC-7801 set: 18mm.

Here’s a photo of the three-piece set of 18mm-long Torx bits that I purchased separately:

I’d have liked to find an assortment of 16mm-long bits but, for my purposes, 18mm is short enough.
