Upholstery Nylon is a heavyweight 100% nylon thread for machine and hand sewing indoor and outdoor heavyweight fabrics. It is a bonded 3-ply nylon thread that is weather, abrasion, and UV resistant.

Review: Good and strong thread - Good and strong thread Review: Exceptional Thread - a Must Buy - This is Excellent high strength outdoor thread. It is UV resistant and very strong. 150 yards goes a very long way. I used it to repair nylon canvas for my cot with a sewing awl and it worked great. I used the Speedy Stitcher sewing awl (B00NO4B9Z4) and it worked great. My palm didn't hurt at all after all those punches - it's bigger bulb handle distributes the pressure in a larger area. I tested the repair area by trying break the stitching and this thread is amazingly strong. As a matter of fact, I tried breaking the thread with my hands and stopped for the fear of cutting my skin. I bought the black and white spool and I'm using to repair buttons on my shirts and jackets. This should last well beyond the life of the fabric. It's slightly thicker than regular polyester thread but the durability is worth it. The nice thing about this synthetic thread is that I melt the loose ends with a lighter and crimp with pliers to prevent unraveling (practice before doing actual sewing) You have to buy a spool of this stuff in both black and white. You'll wonder why you never used it before. I bought an extra spool for my bug out bag - its got tons of uses (repair fabric, fishing line, snare line etc) BTW, if you want to build an Emergency Micro Screwdriver, Sewing Awl, X-acto Knife set, get the following: Commando Precision Pocket Screwdriver (B004FGF6N6), Speedy Stitcher #4 Needle (B00B22101S), #11 x-acto blades pack of 5(B00B22101S). The Needle and x-acto blades fits perfectly in the screwdriver cavity. I recommend to spend a few extra bucks and get the x-acto x3311 which comes with the knife handle and six #11 blades total (B0000DD1N4). ## Features - 100% Nylon - Upholstery Nylon is a heavyweight 100% nylon thread for machine and hand sewing indoor and outdoor heavyweight fabrics - It is a bonded 3-ply nylon thread that is weather, abrasion, and UV resistant - For best results use a size 18 needle and increase stitch length - Packaging may vary ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004BP43JE | | Best Sellers Rank | #42,016 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #432 in Sewing Thread | | Brand | Coats & Clark | | Brand Name | Coats & Clark | | Color | Black, Chona Brown, Green Linen, Soldier Blue, White | | Customer Reviews | 4.7 out of 5 stars 8,295 Reviews | | Global Trade Identification Number | 00073650797408 | | Item Length | 137 Meters | | Item Weight | 0.04 Pounds | | Manufacturer | Vista Partners Inc. | | Material | Nylon | | Material Composition | Nylon 100 | | Material Type | Nylon | | UPC | 073650797408 | | Unit Count | 450.0 Feet | ## Product Details - **Brand:** Coats & Clark - **Color:** Black, Chona Brown, Green Linen, Soldier Blue, White - **Compatible Knitting Needle Metric Size:** 12 Millimeters - **Compatible Knitting Needle US Size:** 18 - **Global Trade Identification Number:** 00073650797408 - **Item Length:** 137 Meters - **Item Weight:** 0.04 Pounds - **Material:** Nylon - **Material Composition:** Nylon 100 - **UPC:** 073650797408 ## Images ![COATS & CLARK Extra Strong Upholstery Thread, 150-Yard, Black (S964-0900) - Image 1](https://m.media-amazon.com/images/I/61AEsuh+6ZL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What is the tensile strength? (don't reply if you don't know. "lots & lots" "heap plenty" and "pretty strong" are not answers.)** A: It’s a heap of plenty lots of strong! Buy it! **Q: will this work in sewing machines?** A: Yes, it does. I use it on my Brother PQ 1500sl. You will need to increase the tension because it is thicker than regular thread. I use a size 18 Schmetz leather needle or the Hlx5 needle recommended for my machine. **Q: How about telling us what Tex size the thread is? Thanks.** A: I compared this thread with small industrial spools and the closest match would be a 69 (tex70) .009 by dial caliper. Similar to jeans, jacket or vehicle upholstery thread. Most home machines should be able to handle this with the right needle. Works perfect for hand stitched repairs. **Q: Would this be good thread to use for backpack repair? I carry a lot of books with me.** A: Yes it definitely would be.I used it to repair my sofa which gets a lot of use.The sofa material will give way before the the thread does. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good and strong thread *by S***I on May 10, 2026* Good and strong thread ### ⭐⭐⭐⭐⭐ Exceptional Thread - a Must Buy *by W***R on March 31, 2015* This is Excellent high strength outdoor thread.
