Air Consumption: 4 Cfm Review: Nothing else like it. - Had a matco one that lasted for years until I broke the direction switch. Bought this one knowing it was the same for much less. It doesn’t replace a full powered 1/2 impact but it can fit in places i would have never tried before. It is the go to for removing sway links or fasteners I fear breaking. With a swivel socket it is comically underpowered and totally worth it. It can still take off most lug nuts. Review: Awesome tool. Strong, light, and small - Awesome tool. It's my go to when I can't get something apart with a standard wrench. I grab it before a bigger impact always because it's light, strong, and the pivoting head fits where standard impacts don't. ## Features - A True Flex-Head Impact Wrench Design That Angles Both Forward And Backwards With The Industry's Shortest Length Head At 3.34" For Fitting An Impact In All New Never Considered Applications - Patented Design Features Innovative Dual Air Intake Motor, Twin Hammer Mechanism For Increased Power And Adjustable Tension 180° Flex-Head With 360° Swivel Handle For Maximum Access - Perfect For Brake Caliper Bolts Or Wherever You Can Hook The Ultra-Slim Impact Head - Front Head Exit Exhaust, 400Ft.Lbs Max Torque, 280Ft.Lbs Working Torque ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01JBP4NGQ | | Best Sellers Rank | #93,992 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #131 in Power Impact Wrenches | | Brand | AP Astro Pneumatic Tool Company | | Brand Name | AP Astro Pneumatic Tool Company | | Color | Red | | Customer Reviews | 4.5 out of 5 stars 755 Reviews | | Finish Types | Painted | | Head Style | Flex | | Included Components | 1/2" Nano Flex-Head Angle Impact Wrench - 400ft/lb | | Item Length | 3.34 Inches | | Item Package Quantity | 1 | | Item Torque | 400 Foot Pounds | | Item Type Name | Astro Tools 1834 1/2" Nano Flex-Head Angle Impact Wrench - 400ft/lb | | Item Weight | 3.52 ounces | | Manufacturer | Astro Tools | | Manufacturer Part Number | 1834 | | Manufacturer Warranty Description | 1 YEAR | | Material | Metal | | Material Type | Metal | | Model Number | 1834 | | Operation Mode | Pneumatic | | Package Quantity | 1 | | UPC | 745227074624 | ## Product Details - **Brand:** AP Astro Pneumatic Tool Company - **Color:** Red - **Item Length:** 3.34 Inches - **Item Weight:** 3.52 ounces - **Material:** Metal ## Images ![Astro Tool 1834 1/2" Nano Flex-Head Angle Impact Wrench - 400ft/lb - Image 1](https://m.media-amazon.com/images/I/61Yk7Jxh4BL.jpg) ![Astro Tool 1834 1/2" Nano Flex-Head Angle Impact Wrench - 400ft/lb - Image 2](https://m.media-amazon.com/images/I/71Y3vAeS8tL.jpg) ![Astro Tool 1834 1/2" Nano Flex-Head Angle Impact Wrench - 400ft/lb - Image 3](https://m.media-amazon.com/images/I/61HjcT+LZTL.jpg) ![Astro Tool 1834 1/2" Nano Flex-Head Angle Impact Wrench - 400ft/lb - Image 4](https://m.media-amazon.com/images/I/61NZSoPUupL.jpg) ## Available Options This product comes in different **Pattern, Size** options. ## Questions & Answers **Q: Do you need to use impact sockets or can you use reg ones?** A: Technically, you can you any socket you want with this. That said, I'd strongly recommend using impact sockets as the regular sockets are pretty soft and will eventually get mangled. By the way, this is a very good impact gun when used appropriately. I found it doesn't have the same level of power as my other impact guns, but it's worth the money when working on brake calipers and other jobs that are too tight for the normal impact guns. **Q: How big of an air compress do I need to use this? I have a 5 gallon porter cable. Will that be enough power?** A: I have a two stage 100 gallon. It all depends on how much you use it. If you zip off a nut only once every couple of minutes, it should do the trick, but if you try to take all the lug nuts off a car in one go, you're going to have to wait for it to catch up. **Q: Does it have enough torque to remove Subaru crankshaft pulley bolt?** A: No, but is enough torque to take out odyssey cam bolts. **Q: How many ugga duggas?** A: it has bunch of ugga ... but a lot more duggas... it is a great gun!!!!! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nothing else like it. *by A***R on March 28, 2026* Had a matco one that lasted for years until I broke the direction switch.

I grab it before a bigger impact always because it's light, strong, and the pivoting head fits where standard impacts don't. ### ⭐⭐⭐⭐⭐ Definitely a handy little fella *by M***. on October 29, 2025* Got it a little over a year ago and this air wrench is VERY nice to have around in our shop. I got the 1/2 inch but it still fits pretty much everywhere we want to use it on, it definitely saves doing some yoga if you were using a normal air wrench when pulling beds/engines/transmissions/body mounts/etc. I’ll also mention that it is pretty light too while still keeping the speed and power it had when we first bought it even after over a year of using it fairly often (probably 1-3 sessions with it per week if I had to guess) so it’s pretty durable id say though I haven’t tried any other Definitely a quick to set up and strong little tool to have around id recommend it ## Frequently Bought Together - Astro Tools 1834 1/2" Nano Flex-Head Angle Impact Wrench - 400ft/lb - Astro Pnematic - 15Pc 1/2" Drive Low Profile Nano Impact Sockets - Metric (model: 78215) - Astro Pneumatic Tool 78244 11Piece 1/2" Drive Nano Pinless Universal Impact Sockets - Metric --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/270070238-astro-tool-1834-1-2-nano-flex-head-angle-impact](https://www.desertcart.tw/products/270070238-astro-tool-1834-1-2-nano-flex-head-angle-impact) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-05-20*
