Discover how the Lockit Socket spark plug socket simplifies spark plug service by eliminating a little nuisance that's been around forever: the rubber socket insert. These inserts grip too tightly when new, won't hold a spark plug when they're worn or oily, and take up space, making the socket diameter larger. Many technicians mistakenly think the rubber insert cushions the spark plug. In reality, because the rubber insert holds the spark plug by gripping the porcelain, insulator breakage can result when this type of socket is forced sideways. With some of the spark plugs for newer vehicles costing upwards of $30.00, breakage is just not acceptable.
Worn Rubber Inserts Lead to Dropped Spark Plugs!
Impact from dropping a spark plug due to a worn out insert can bend and weaken the electrode. Depending on where it lands, the plug can become contaminated from grease, oil or coolant. In fifteen years as a mobile tool distributor, the Lockit Socket spark plug socket generated more favorable customer comments than any other single tool I can think of. Automotive, marine, and motorcycle technicians love the way these sockets make their jobs easier.
Here are some typical responses:
Gary, I was so pleasantly surprised on Monday evening when I got home and got my mail. My new "Lockit Socket" was waiting for me. Wow! The design and craftsmanship are top notch. Thanks again for such fine tooling.
Your favorite toolaholic,
-Rich Ploeser, Dual Master ASE certified trainer.
As a Technical Service Engineer with Champion Spark Plug for forty years, I changed a lot of spark plugs. By far, the best spark plug socket design that I ever used was the one now made by Lockit Socket.
The additional designs that you have introduced make it an even better buy than before and that is hard to do. I totally endorse your product and I hope that technicians will give them a try. Unless they leave them under the hood or loan them to another technician, this will be the last spark plug socket they will ever purchase. Best of success to you and your company.
Sincerely, Ken Friedman

Lockit Socket tools are two time winners of Professional Tool & Equipment News magazine's Innovation Award:
This prestigious award is given to manufacturers of tools or equipment that change the way a service has been performed, increase safety, save time or make the process more efficient.

- You'll save time and effort thanks to the positive grip and easy release made possible by the patented Lockit Socket spring clip retention design.
- Spark plug insulator damage is a thing of the past due to the thin outside profile and added roominess inside the Lockit Socket.
- The aggravation you may have experienced when your oil slick hands couldn't retrieve a spark plug socket will be a thing of the past. The superb grip of the ‘gnarly gnurl' will be a pleasant surprise!
Some of today's high performance Iridium spark plugs cost upwards of $30.00 each. Preventing damage to just one of these spark plugs pays for most of the $44.95 price of the most expensive Lockit Socket. For technicians working at current shop rates (usually $80.00 and up), saving less than ½ hour over time repays the purchase price. The convenience is an added bonus!
The Lockit Socket spark plug socket has a lifetime unconditional guarantee against any defects or breakage. While damage to the replaceable spring clip is very rare, a spare spring clip is included with the purchase of each tool, just in case.
Try Lockit Socket tools for 90 days, and if you're not entirely satisfied, return them for a full refund. We're confident that once you've used these tools, you'll never give them up!
9/16" Socket for Ford Triton Spark Plugs
Out Of Stock
Newer Ford 5.4 liter engines have deep spark plug tubes with unique 9/16" plugs. Our new 9/16" Lockit Socket is the perfect tool for servicing these vehicles. The 5/8" external hex and long length allow for use with a ratcheting box wrench. This is especially helpful under the overhanging cowl found on Ford trucks. Since no extension is necessary, there is less flex when installing new plugs, which minimizes the chance of cross threading. The reduced diameter through the middle of the tool improves access into the spark plug tubes. Size: 9/16" Overall length 6".
