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 - An industry first true flex-head impact wrench and with our shortest length yet at 3.34" - Patented design features innovative dual air intake motor and twin hammer mechanism for increased power, and 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01JBI182U | | Best Sellers Rank | #88,791 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #132 in Power Impact Wrenches | | Brand Name | AP Astro Pneumatic Tool Company | | Color | Black | | Customer Reviews | 4.5 4.5 out of 5 stars (750) | | Finish Types | Powder Coated | | Head Style | Flex | | Included Components | 3/8" Nano Flex-Head Angle Impact Wrench - 400ft/lb | | Item Length | 3.34 Inches | | Item Torque | 400 Foot Pounds | | Item Type Name | Astro Tools 1833 3/8" Nano Flex-Head Angle Impact Wrench - 400ft/lb | | Item Weight | 3.5 Pounds | | Manufacturer | Astro Tools | | Manufacturer Warranty Description | Manufacturer’s Warranty | | Material Type | Aluminum | | Model Number | 1833 | | Operation Mode | Pneumatic | | Package Quantity | 1 | | UPC | 745227077335 | ## Product Details - **Brand:** AP Astro Pneumatic Tool Company - **Color:** Black - **Item Length:** 3.34 Inches - **Item Weight:** 3.5 Pounds - **Material:** Aluminum ## Images ![Astro Tool 1833 3/8" Nano Flex-Head Angle Impact Wrench - 400ft/lb - Image 1](https://m.media-amazon.com/images/I/51IpIpRaJhL.jpg) ## Available Options This product comes in different **Pattern, Size** options. ## 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.
