Williams Tools' Proud History

Williams has made strong, trusted tools for industrial professionals with pride since 1882. It’s first factory in Red Hook, Brooklyn, NYC, revolutionized drop forging, “blacksmithing by machinery,” to ensure all pieces were created with the same consistency and quality. Due to their precise manufacturing process, Williams’ products were used in the countless industrial shops of 19th century America.

Williams: The Industrial Workhorse

Symbolic of the Williams brand, the workhorse prides itself on putting its head down, working hard for you and delivering valuable results to your work. We recognize the need for getting back to the basics: the importance of a job done well, every time, with confidence and pride. Williams’ heritage of high-quality, industrial-focused tools continues to deliver a brand of tools that is ready to work.

Williams Wrenches

Not just heavy duty. Industrial duty.

Quality Wrenches Since 1882

Leverage

Maneuverability

Strength

SuperCombo wrenches have super leverage.

Williams rounds the edges on their SuperCombo wrench bodies for maximum comfort and ease of use.

The tighter the access, the better the performance in confined space.

Competitor's wrenches allow only 30˚ access then engaging with a fastener. This means you'll use your wrench in fewer areas, especially those tough-to-reach spots where you need access the most. Williams wrenches allow 15˚ access, which means more turning capability and more use in tight areas.

Strength you can count on.

The continuous arc design of a Williams wrench provides exceptional performance while reducing chance of failure and breakage.

Williams Ratcheting Wrenches

Williams Ratcheting SUPERCOMBO Wrenches

  1. SUPERCOMBO Open End: has specially designed grooves that direct wrench force away from fastener corners and onto the flats preventing rounding of fasteners
  2. Longer Length Wrench Handle: sized for optimum comfort and balance that provides increased leverage
  3. Manufactured From Special Alloy Steel: precision forged and heat treated for optimum strength and durability; high polish nickel-chrome plating textured finish provides great feel and wipes clean easily
  4. Low Profile, Easy Action, Reverse Lever: won’t get in your way
  5. Ratcheting Gear: up to 80 teeth minimize the swing arc in tight spaces
  6. SUPERTORQUE Box End Design: allows application of higher torque without rounding or deforming hex fasteners points

Fits tight without slop. Has a nice offset to get your hands away from whatever you're working on. Has a little bit thicker ends than other brands. That could be a pro or a con depending on what you're doing. Might not fit into a tight space without a lot of clearance but should keep it from breaking if you really have a tight bolt.

I purchased this tool hoping the 10 degree offset would fit size 15 nut on idler pully which has tight clearance and requires the offset to loosen tensioner pully. This fits well and paired with extension tube allows for easy removal of Honda CR-V 2002-2006 serpentine belt.

3.0 out of 5 stars Angled box openings
Reviewed in the United States on June 5, 2023
Size: 10 by 12 millimetersStyle: MetricVerified Purchase
I bought two of these wrenches in commonly used sizes and I'm disappointed. The weight, length, and feel are pretty good, but all four box openings were irregularly ground. They fit the nut ok, but the opening is off center and slightly angled, leaving a thinner edge on one side. I don't know how they got through quality control that way, but here we are. This is the first Williams product I've been unhappy with.

Size: 1/2-Inch by 9/16-InchStyle: ImperialVerified Purchase
The wrench is high quality. The description is inaccurate. It says it is 15cm (something I could throw in my pocket for the day around the farm and something I use regularly) but the wrench that came is actually twice that length. I wanted to exchange it for a shorter one but cannot select anything useful in the limited items that come up for exchange. Frustrated with the whole process.
