Review: Great price for this adapter - Wasn't sure what to expect, but it seems to be machined correctly and it fit perfect. Review: Threads True, Fit Perfect — Held Up Under Pressure - Picked this up to adapt 1/2x28 to 5/8x24, and it did exactly what it was supposed to. Threads were clean, concentric, and snug—no wobble, no hassle. The included washer was a nice touch and made installation smooth. I tested alignment with a precision ground rod, and it was spot on. Even under high-pressure situations, the threads held up beautifully with no signs of stress or misalignment. If you're looking to run different muzzle devices or just need a solid adapter that actually lines up right, this one does the job perfectly. Great price, rugged, and no surprises—just the way it should be. It's a lot cheaper than the other options out there, not sure if I got a perfect one that was made on Wednesday, but mine works great. For the price, it's worth a shot. ## Features - Steel 1/2x28 Thread Protector - 1/2x28 Convert to 5/8x24 - Black Oxide Finish All Steel Construction ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08CGJ61P4 | | Best Sellers Rank | #59,405 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #14 in Externally Threaded Inserts | | Brand | TACBRO | | Color | Black | | Compatible Groove Diameter | 0.63 inches | | Customer Reviews | 4.5 out of 5 stars 428 Reviews | | Exterior Finish | Black Oxide | | Fastener Type | Hex | | Finish Types | Black Oxide | | Grade Rating | industrial | | Inside Thread Size | 5/8x24 | | Item Diameter | 0.5 inches | | Manufacturer | US-DEALS | | Material | Alloy Steel | | Material Type | Alloy Steel | | Metal Type | Alloy Steel | | Outside Diameter | 0.5 inches | | Screw Head Style | Flat | | Size Name | 1/2 inch x 1/4 inch | | Thread Class | Class 2A | | Thread Size | 1/2 inches | | Thread Style | Right Hand | | Thread Type | Unified National Coarse (Unc) | ## Product Details - **Color:** Black - **Exterior Finish:** Black Oxide - **Fastener Type:** Hex - **Material:** Alloy Steel - **Thread Size:** 1/2 inches ## Images ![DEALS US Black Steel 1/2x28 Thread Protector, 1/2x28 TPI Convert to 5/8x24 TPI with A Washer - Image 1](https://m.media-amazon.com/images/I/41979uqr00L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great price for this adapter *by Z***G on April 29, 2026* Wasn't sure what to expect, but it seems to be machined correctly and it fit perfect. ### ⭐⭐⭐⭐⭐ Threads True, Fit Perfect — Held Up Under Pressure *by J***. on May 7, 2025* Picked this up to adapt 1/2x28 to 5/8x24, and it did exactly what it was supposed to.
