Ideal for low-strength assemblies and brittle materials, these plain finish nuts are precision-engineered in the USA to deliver reliable, quick fastening with lasting hold. ## Description Most often used on machine screws and threaded rod, these general purpose nuts are for low-strength assemblies. Hex Nuts have flat tops with chamfered corners; bottoms may be flat or chamfered. Hex drive systems are driven with a wrench.Steels are designated by a 4 number SAE Steel grade. The first two digits indicate the primary materials used to form the steel. The last 2 digits identify the percentage of carbon for the alloy (in hundredths). The steel used in these fasteners has a tensile strength ranging from 100,000 to 150,000 psi (pounds per square inch).A threaded fastener's size name includes information about the major external diameter (in millimeters), followed by the thread pitch (millimeters per thread), which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings. Review: Correct size, sturdy steel - The ones I have used work as they should, no problems with the threads not working. They are the right size and shape. From what I can feel they are high quality metal that you do not have to worry about breaking. Review: What was needed. - Deez Nutz! And a lot of them - 100. ## Features - Hex Nuts are appropriate for use in low-strength assemblies - Plain Steel fasteners are suitable where strength and value are the primary considerations - Drive system is a hexagon-shaped head - Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads - Ensure a lasting hold for any project ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000NBIH92 | | Best Sellers Rank | #776,575 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #2,506 in Hex Nuts | | Brand | Small Parts | | Date First Available | April 1, 2006 | | Exterior Finish | Plain | | Fastener Type | Hex | | Inside Thread Size | M 3 | | Is Discontinued By Manufacturer | No | | Item Weight | 0.01 ounces | | Item model number | B000NBIH92 | | Manufacturer | Small Parts | | Material | Alloy Steel | | Metal Type | Alloy Steel | | Size | M3-0.5 | | Thread Size | M3-0.5 | | Thread Type | Unified National Coarse | ## Product Details - **Exterior Finish:** Plain - **Fastener Type:** Hex - **Material:** Alloy Steel - **Metal Type:** Alloy Steel - **Thread Size:** M3-0.5 ## Images ![Steel Hex Nut, M3-0.5 Threads, Made in US (Pack of 100) - Image 1](https://m.media-amazon.com/images/I/81jMPv3gkvL.jpg) ## Available Options This product comes in different **Item Height String, Thread Size, Number Of Items, Item Width String** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Correct size, sturdy steel *by D***S on December 25, 2014* The ones I have used work as they should, no problems with the threads not working.

They were exactly as described. I can't really give them 5 stars because they are just nuts. --- ## 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.pl/products/77406279-steel-hex-nut-m3-0-5-threads-made-in-us](https://www.desertcart.pl/products/77406279-steel-hex-nut-m3-0-5-threads-made-in-us) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-26*
