1/2" Scissor Jack Adapter, Scissor Jack Drill Adapter for 1/2 Inch Drive Socket or 13/16 Inch Lug Wrench, Drive Impact Wrench Automotive Sturdy Power Jacks Connector

A scissor jack is turned by a screw, and that screw takes a socket. This is the coupler that sits between the screw and a drive tool. It is a simple piece of steel with a specific job, and the sensible way to buy it is knowing exactly what the supplier does and does not state about it.

What the steel actually is

Chrome-vanadium is the material given, which is the usual choice for sockets and drive tools because it takes torsional loading without shearing. The body measures 0.8 x 2.0 inches, roughly 20 x 51 mm, and weighs 0.3 lb, about 136 g. The bore is given as 0.5 inch and the outside as 0.8 inch. The supplier lists it as suiting 1/2 inch drive tools, ratchets and socket adaptors, and 13/16 inch lug wrenches. Note that no torque rating and no load rating appear anywhere in the data, so there is no published figure for what this adapter will take.

A jack lifts a vehicle. It does not hold one up

This is the part that matters more than any specification. A scissor jack is a lifting device, and nothing more than that. Once a vehicle is at height, axle stands rated for the load go under the manufacturer's designated support points and carry the weight before anyone puts a hand, an arm or a head under the car. The jack stays in place as a backup and is never relied on. Level, firm ground, the handbrake on, the vehicle in gear or in park, and the diagonally opposite wheel chocked, are the conditions before the jack is touched at all.

Read this before a drill goes anywhere near a jack

Driving a scissor jack with a power tool removes the feedback a handle gives you. The screw has a finite travel and a jack run to the end of it can strip the thread, bind, or tip the vehicle off the jack head. An impact wrench makes that far worse: it delivers hammer blows the screw was never designed to absorb, and it will reach the travel limit before you have registered anything is wrong. Use a low-speed drill at most, keep a hand on the vehicle to watch what is moving, and stop well short of the jack's stated travel in both directions.

Key features

• Chrome-vanadium steel: the material the supplier names for the body.
• 0.5 inch bore: the internal dimension published for the drive end.
• 0.8 inch outside: the external dimension, listed as suiting a 13/16 inch lug wrench.
• 136 g: light enough to live in a boot kit rather than a workshop drawer.
• 51 mm long: a short coupler, not an extension bar.

Safety rules that are not optional

• Never work under a vehicle supported by a jack. Rated axle stands take the load at the manufacturer's support points first, every time.
• Never use an impact wrench on a scissor jack. The screw is not built for impact loading and the travel limit arrives faster than you can react.
• Only lift on level, firm ground. Soft gravel, a sloped driveway or hot bitumen can let a jack lean or sink under load.
• Stop well before the top and the bottom of the jack's travel. Running a screw jack against its stops under power is how threads are stripped and jacks are toppled.
• No torque or load figure is published for this adapter. Do not assume it will carry whatever your tool can deliver.
• Check the fit against your own jack before relying on it. No jack make or model is named anywhere in the supplier's data.
