There is not enough clearance to sit comfortably. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Work well but look/feel cheap *by T***L on Reviewed in the United States on November 12, 2020* I will buy again when I run out.Upon first touch and appearance, I thought these were cheap junk. HOWEVER, they actually work well which is what matters. I have not melted any of them with the soldering iron or heat shrink gun. The screws are captured, so they cannot accidentally fall out if you loosen them all the way. I have used them with 22 AWG wire and so-called "premium prototyping wires", and have not had any come loose from vibration or other causes at this point. They solder easily into 0.1" spaced holes. Really the only thing I don't like is that on a breadboard pattern circuit board, you can only put two adjacent 4-position terminals next to each other without leaving a one hole gap between the pairs (i.e. 8 termination points, 1 point gap, 8 termination points). ### ⭐⭐⭐⭐ 4.0 out of 5 stars Great terminal blocks *by W***Y on Reviewed in the United States on August 4, 2019* The terminal blocks are exactly as stated by the seller. They are spaced at 2.57mm (0.1 inch) and fit the blank prototype boards that I purchased earlier. The only reason it didn't get five stars is that one of the terminal blocks did not have any screws in it and they were not in the bag. Otherwise all is well. --- ## 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.vu/products/118194397-touhia-2-54mm-pitch-4-pin-pcb-mount-screw-terminal](https://www.desertcart.vu/products/118194397-touhia-2-54mm-pitch-4-pin-pcb-mount-screw-terminal) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-14*
