I use the Innovative Components 1.75" Star Knobs for the UTV door extensions I manufacture and sell, and they are worth every penny. When you’re selling a product to the off-road community, the hardware has to be "overbuilt," or you’re going to hear about it. The build quality is exceptional. The threading is precise and consistent across every batch, which is critical for my production. The 1.75" diameter provides the perfect amount of leverage for customers to tighten or remove the extensions by hand—even with cold hands or riding gloves on. I specifically choose these because I refuse to have customers complaining about cheap, stripped, or cracked hardware. These knobs feel premium, stay secure under vibration, and add a professional, finished look to my gear. If you are a maker or a shop owner who values reputation and reliability, these are the only knobs you should be using. Review: A Good Value ! - With a 1/4-20 insert and a larger Counter Bore allows this to be used in multiple ways! I'm using a #10-32 screw with a standard washer and found it easily adapted to my application. Slight deburring might be needed to remove some sharp corners, otherwise the form factor is good. So I'm attaching the knob to something with a smaller screw, but it can also be used with a stud on your part and tightened down, or used to hold something which can be easily released. Pretty useful! ## Features - Popular choice with smooth lines and finger grip spacing for easy turning - Contemporary Satin Textured Finish ,Scratch and Dirt resistant - Won't crack, become brittle or discolor - AN4C-5S3A-21 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00GORXQNG | | Best Sellers Rank | #430,515 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #287 in Star Knobs | | Brand | Innovative Components | | Brand Name | Innovative Components | | Color | Black | | Customer Reviews | 4.7 out of 5 stars 207 Reviews | | Included Components | Knob | | Item Diameter | 1.75 inches | | Item Dimensions | 7 x 5 x 1.5 inches | | Item Weight | 18.14 g | | Item dimensions L x W x H | 7 x 5 x 1.5 inches | | Manufacturer | Innovative Components | | Manufacturer Part Number | AN4C----4S3A-21 | | Material | Alloy Steel | | Material Type | Alloy Steel | | Model Number | AN4C----4S3A-21 | | Number of Items | 10 | | Number of Packs | 1 | | Style | Contemporary | | Style Name | Contemporary | | Unit Count | 10 Count | ## Product Details - **Brand:** Innovative Components - **Color:** Black - **Item Weight:** 18.14 g - **Item dimensions L x W x H:** 7 x 5 x 1.5 inches - **Manufacturer:** Innovative Components - **Material:** Alloy Steel - **Number of Items:** 10 - **Style:** Modern - **Unit Count:** 10 Count ## Images ![AN4C-5S3A-21 1.75" Star Knob thru hole 1/4-20 steel zinc insert black pp (Pack of 10) - Image 1](https://m.media-amazon.com/images/I/612zICbRiOL.jpg) ## Questions & Answers **Q: So "free spinning" means once screwed on, the knob continues to spin?** A: In this sense "free spinning" means it does not have a nylon locknut type ring. Their sister product, B00GORY4E6, has the nylon ring to provide some grip to resist loosening due to vibration, etc. **Q: is this good for 8m screws?** A: No, these are for 1/4x20 bolts. An 8mm screw is too big and will have a different thread. **Q: what is the quantity,1 place says 1 and another says pack of 10?** A: My package was 10 knobs. The add says 10 knobs in 1 package so you get 10. **Q: Do these have the nylon lock washer inside? the picture is the same cgi as the other offering.** A: No nylon lock washer. Just metal thread insert. ## Customer Reviews ### ⭐⭐⭐⭐⭐ ⭐⭐⭐⭐⭐ Professional Quality – The Standard for My UTV Builds! *by M***E on April 26, 2026* Not a Vine review.
