Product Details

The Performance Tool W38318 is a professional-grade deep socket designed for accessing fasteners in recessed or hard-to-reach areas. This 9/16-inch socket features a 3/8-inch drive size, making it compatible with standard 3/8-inch drive ratchets, extensions, and torque wrenches.

Key Features:

  • 3/8-inch drive size for versatile use with standard drive tools
  • 9/16-inch socket opening fits SAE fasteners precisely
  • 6-point design provides superior grip and reduces fastener rounding
  • Deep socket construction reaches recessed nuts and bolts
  • Constructed from vanadium alloy steel for exceptional strength and durability
  • Polished nickel chrome plating resists corrosion and wipes clean easily
  • Standard length deep socket suitable for automotive, marine, and general mechanical work

Vanadium alloy steel construction provides the strength needed for professional applications while resisting wear and deformation. The 6-point design grips fasteners on all six sides, distributing torque evenly and minimizing the risk of rounding off bolt heads. The polished chrome finish not only looks professional but also makes it easy to identify socket sizes and provides long-lasting corrosion resistance.

The only thing I would like to know is what the manifold kit comes with for hardware. Its not specified if they come with any hardware or gaskets at all and i would like to be prepared to do the job when they arrive in the mail.

Very fast, clear and secure order placement but there was a problem with the mails. My shipping address was different than my billing address. On the confirmation mail the names were changed while your website showed it correct. It was a little confusing.

Good pricing.

I was happy to find this item that was unavailable from several web stores.

I found what I wanted and it was overall a pleasant experience.

Straight up , seamless process

Quick and easy. I just hope it works for my application:)

Smooth transaction! Best price on the floor liner I was looking for, shipped promptly with tracking info provided, exactly as advertised. THANKS!!
