Review: Excellent construction, very handy for mounting a lug bag gauge to a base - It's difficult to tell, but the piece looks like it's in a natural finish in desertcart's picture. The one I received appears to be black anodized. Overall, it's perfect for mounting a lug back gauge onto a magnetic base or fixture. Typical quality from Starrett (if we're only talking about their products still made in the USA).

The one I received appears to be black anodized. Overall, it's perfect for mounting a lug back gauge onto a magnetic base or fixture. Typical quality from Starrett (if we're only talking about their products still made in the USA). ### ⭐⭐⭐⭐⭐ Great product for dial indicators *by S***S on May 30, 2025* I use mine as an adapter to put my digital indicator on my support arm while taking critical measurements on aircraft. ### ⭐⭐⭐⭐⭐ Excellent quality, typical Starrett *by B***D on June 7, 2017* Excellent quality, typical Starrett. However, the 1/4" stem did not fit my 8mm Noga mag base clamp. I made a split collet out of an 8mm bolt by drilling the bolt out 1/4", cutting it down to about 10mm long, and splitting it along the side with a slitting saw. Now I can use this with my lug backed Mitutoyo indicator and Noga mag base. --- ## 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.es/products/13587494-starrett-indicator-attachment-for-agd-lug-backs-1-4-o](https://www.desertcart.es/products/13587494-starrett-indicator-attachment-for-agd-lug-backs-1-4-o) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-08-23*
