Zero Degree 38150 Ultra-Precise Gearless Ratchet – Nickel Plated High-Carbon Steel with ASME Certified Torque – Durable & Rust-Resistant – Perfect for Tight Spaces, 1/4" Drive

After reading negative reviews on Amazon & local box stores, I purchased the 3/8” version of this gearless ratchet. It worked perfectly to remove & tighten the infamous starter mounting bolts on the ‘04-‘08 F150 three-bolt starter (top bolt), as there is virtually no room for a standard ratchet with backdrag to get a single click. Before use, I disassembled it (snap ring) and greased the head with white lithium (it was already lubricated with a light oil out of the box). Be careful if you disassemble it because the roller bearings will fall out; make sure the ratchet is horizontal when pulling out the guts & stand in an area where the roller bearings can be easily found should one or more fall out. (I was fortunate to find one that disappeared in a cluttered overstocked residential garage.) Notes: 1) I broke the starter mounting bolts with a standard 72-tooth ratchet, as I suspect the gearless ratchet is rated only for lower-torque applications. 2) The direction-switch lever is a tad rough, but it doesn’t affect ratchet performance. 3) The release button & drive gear are solid & operationally smooth. 4) Consider using a grease lighter than WL or stick with an oil lubricant. [Even though this is a specialty tool that will most likely spend more time in the tool bag than in my hands, I am contemplating purchasing the 1/4” version.]

Small but mighty — perfect for tight spaces and precision work I’m very happy with this Zero Degree 3/8" gearless ratchet. It’s compact, well‑made, and gives excellent control in tight areas where a conventional ratchet won’t fit. The gearless mechanism lets you turn fasteners with virtually no wasted motion — great for under dash work, engine bays, or any confined spot. The nickel finish resists corrosion and the head feels solid; sockets lock on securely. Pros: - Extremely low swing arc — ideal for cramped spaces - Positive, precise engagement — good for delicate/precision tasks - Compact, sturdy construction and corrosion‑resistant finish - Comfortable handle and easy socket changes Minor cons: - Not as smooth when spun freely compared with high‑end full‑size ratchets (doesn’t affect performance in tight work) - If you need heavy torque frequently, a larger ratchet is still preferable Bottom line: A great addition to any toolbox for mechanics, DIYers, and anyone who frequently works in confined spaces. Highly recommended for precision and accessibility.

I absolutely love this ratchet. It works so well when rotation is confined. It seems to be built extremely well and is so smooth in operation. Even so, I don't subject it to very heavy torque (or hitting it with a mallet ect) -- if needed, I'll use one of my geared ratchets to take any abuse...otherwise it's my go-to.

This press is solidly built, the gearless mechanism works smoothly, and it applies even pressure every time. The design is compact, the handle grip is comfortable and easy to turn. I love how precise it feels, small adjustments make a real difference. It’s well made, durable, and worth every penny. Great tool for consistent results.

I did really like this ratchet but after about 6 months it started binding occasionally then completely locked up. I took the mechanism out and found the cage (which appears to be plastic) broken in multiple places. Product say it has a lifetime warranty but I have been searching for a way to contact Zero Degree for a few days and cannot find anything. If they reach out with a way to warranty this then I have no problem editing my review as this was a really great ratchet until it failed and I was about to get the 1/4 inch version to accompany it EDIT: I was able to find a way to contact the vender thru a different website and they got me a replacement within a week. If anyone else needs to get thiers replaced, go to alliedtools.com.

Great ratchet, makes removing nuts and bolts much faster.

I bought the 1/4 inch version a while ago. I was very happy with is so I decided to get the 3/8 ratchet. There is virtually ZERO degrees of swing before the internal bearing engages. Back drag is very low. The head is a little then a standard ratchet. For me, this is more of a tool for when a standard ratchet just will not work. I do not plan on using this day to day, but only when I need that extra little of grab when I have very little room to use a standard ratchet. The chrome quality id very good. The markings on the handle is laser etched. I much prefer stamped markings. But it is a minor thing. As you can see in my photo, the socket has a pretty large gap under the ratchet head. I got mine on sale, so overall I am very happy with it. Since I have he 1/4 and 3/8 ratchets, I do not think I will have a need for the 1/2 since I think this more of a specialty tool.

I am a private deasile mechanic. Already ussing these tools and absolutly love them. They are smooth in motion and work verry well in tight places.

Esta herramienta es excelente la vdd no le he exigido solo la uso para casos donde se necesita y me ha sacado de apuros

Very good. Just what i need.

Funktioniert unter 1°. Für hohe Drehmomente nehme ich sie Sicherheitshalber nicht.

all good

Fantastic invention I don't know how much torque you can put on it but so far works like a charm
