Williams SNPS-110P 1/2" Dr Extension 5"

The Williams SNPS-110P is a 1/2 inch drive extension, 5 inches.

Note that the source states no finish. That matters more than it looks: this range carries both chrome extensions and impact extensions, and they are not interchangeable. A chrome extension on an impact gun is hardened steel taking thousands of hammer blows a minute, and it snaps — Williams' own warranty states that using chrome-finish tools on power drive equipment is a misuse that can cause serious injury. Verify the finish before publishing.

The 5 inch length is the general working extension and it is the one most people reach for.

What an extension buys is reach past an obstruction. What it costs is feel and torsional stiffness. An extension is a steel bar transmitting torque, and under load it twists — elastically, a little, and more the longer it is. The operator's hand feels the wrench move before the fastener does, which makes a delicate job harder to judge.

It also costs alignment. A socket on an extension can be run at a slight angle to the fastener without anyone noticing, and a socket that is not square on a nut rounds it.

Five inches is the length that clears most obstructions without losing much of either.

Applications include automotive, equipment, and machinery.
