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

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.

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.]

Great item. Works when others won't. Gave it to my grandson, who is a mechanic, and he uses it all the time.

My husband needed this exact ratchet, and he was pleasantly surprised at the quality and durability of it. It is nice to find a dependable tool on Amazon.

I have the 1/4, 3/8 and 1/2. Just for reference, I also have another brand of gearless ratchet. The 3/8 amd.1/2 seems to works well with near zero slack. The 1/4 however doesn't work so well. Granted it still has way less slack than geared ratchets, it still have enough slack that you notice. Though this 1/4 has some slack, it is less than my other 1/4 gearless ratchet. I have put to under load yet but I don't expect gearless to be as strong as geared.

Great seller quick shipping 100% satisfied and five stars for him. Thank you very much.

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.

Great ratchet, makes removing nuts and bolts much faster.
