It is good quality and works well Review: Fabulous Product! - I ordered a set of antique door knobs to replace the set that broke. I knew the spindle that came with the knobs wouldnt be the right size. This was the right length and thickness for my antique front door. I added a thin piece of Surgical Tape tonight to hold it exactly into place (because its an antique door and I was afraid it might be wobbly.) . Its perfect. Exactly what I needed. I am going to order another one very soon to have a back up spindle. Thank you. ## Features - Straight Square Spindle - 9/32" X 5" - 20 TPI ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0725G2413 | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #198,744 in Automotive ( See Top 100 in Automotive ) #19 in Automotive Replacement Spindles | | Color | Gray | | Customer Reviews | 4.2 4.2 out of 5 stars (96) | | Date First Available | May 8, 2017 | | Is Discontinued By Manufacturer | No | | Item Weight | 1.76 ounces | | Manufacturer | Tuff Stuff | | Package Dimensions | 5.43 x 1.57 x 0.79 inches | | Part Number | 4425 | | Shape | Square | ## Images ![Tuff Stuff 4425 9/32" X 5" Straight Square Spindle - Image 1](https://m.media-amazon.com/images/I/31XAl4Ok3NL.jpg) ## Questions & Answers **Q: Hi what metal is this made from please?** A: I believe it is steel.

Thank you. ### ⭐⭐⭐⭐⭐ Thicker than the competition *by R***N on January 16, 2025* All of my doors are outfitted with Prime Line knob sets, all of those have suffered from spindles that are way too short and too thin to hold the set screw in place. Every single knob has come loose over the past year, depending on use. I got this spindle and immediately feel the difference for the better, the knobs are sitting nice, tight and snug; giving that sturdy feel to the door. So thanks to Tuff Stuff. ## Frequently Bought Together - Tuff Stuff 4425 9/32" X 5" Straight Square Spindle - Progressive Hardware Co.
