How the Locking Mechanism Works

Push sockets onto the drive tang to lock them on; pull down on the collar to release. Sockets stay seated at any angle, in any position.

Materials & Build

Each extension is made from 6140 chromium-vanadium steel with an 8660 nickel-chromium-molybdenum collar and chrome plating for corrosion resistance. Deep knurling provides grip for turning fasteners by hand; grooves ease socket changes.

Locking collars actually work

The push-lock collars hold sockets firmly, no more dropping 10mm sockets in deep engine bays. All three lengths feel solid and the chrome finish looks great after months of use.

Great value

At this price you can't beat it. Tekton quality is consistent.

Good set, collar takes getting used to

The locking mechanism works well once you get the hang of the collar. Slight wobble is normal for extensions, but no slop in the drive itself. The 10-inch reaches places my old 6-inch couldn't.

Perfect for spark plugs and brackets

I use the 6 and 10 inch constantly on brake hardware and intake manifolds. The lock feature is a genuine time-saver when working overhead. Would buy again.

Decent but one collar was stiff

Functions fine overall, but the collar on my 3-inch extension is noticeably stiffer than the other two. Still locks and releases, just needs a firm thumb.

One extension arrived damaged

The 10-inch had a bent collar out of the box. Return process was easy but annoying. The other two work fine.

Old school mechanic approved

Been wrenching 35 years and these are as good as sets costing three times as much. Locking feature saves fingers and frustration. The sizes cover 90% of what I do with a 3/8 ratchet.
