The other 1/4 pins are only 6MM, ours is 6.3MM, this is the standard 1/4 pin。 If you encounter any problems during use, please contact us, we'll do our absolute best for you to put things right. **Q: Your description of this product says it is a square shaft but every photo you have shows a round shaft? Which is this please?** A: We usually say that the square shaft locking pin is a pin that can be used on a square shaft or a square tube. The spring wire of the square pin is square, so you can put it on the square tube and insert the pin into the pin hole of the square tube. Since most pinholes are round, we make the needle round. This square pin is also suitable for cylindrical pins. If the pinhole is square, it can be used as long as the size is comparable. hoping it is helpful to you. Thank you for your question. **Q: Does this work with scaffolding?** A: Probably too light duty... I don't believe they would be strong enough for scaffolding application **Q: Is this PTO shaft locking pin easy to use?** A: Yes,it's great! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Holds solid *by K***K on 9 December 2024* ### ⭐⭐⭐⭐⭐ Good locking pin,no surprises *by G***Y on 9 January 2026* ### ⭐⭐⭐⭐⭐ Excelente *by A***A on 4 August 2023* El producto llego muy rapido con su empaque y bolsa nuevo sin ningun detalle lo recomiendo ## Frequently Bought Together - Square Pto Pin Shaft Locking Pin 1/4 pin Hitch pin Wire Lock Pin Safety Coupler Pin 1/4" x 2-3/4"for PTO,Farm,Lawn,Hitches,and Garden (1/4-001) - MaxxHaul 50565 3 Pack Trailer Hitch Pin & Clip with Rubber-Coated Vinyl Yellow Grip, 5/8" Diameter, Fits 2" Receiver - Yoliko Heavy Duty Hitch Pins - 12 Pcs Spring Retaining Wire R Clips M3x60mm for Trailer Tractors Mower Carts Trucks --- ## 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.tn/products/379861356-10-pcs-square-pto-pin-square-shaft-locking-pin-1](https://www.desertcart.tn/products/379861356-10-pcs-square-pto-pin-square-shaft-locking-pin-1) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-02*
