How I wish these were being made about 20 years ago!!!!

It's a simple yet brilliant idea...19 mm two pound impact socket for breaking free crank pulley bolts. The extra mass truly makes a difference in the effectiveness: think "bigger hammer".

I had tried breaking loose the crank bolt on my work van (Honda Odyssey) using my electric impact (no compressed air at home) and a normal 19 mm impact socket and couldn't get anywhere with it. I ordered one of these sockets and started over on the job. About five seconds of brrrrt and then the satisfying whine of the bolt spinning out.

I HIGHLY recommend this for anyone who does Honda T belts. Well worth the money.
