What is this? A Super Convenient Little Tool!
Hello there! Are you tired of struggling with screws that are hidden in tight corners or need to be adjusted frequently? Say hello to our star product – the Star Knob!
Simply put, it’s a screw with its own little handle. This star-shaped grip is super comfortable to hold, allowing you to tighten or loosen screws with just your hands – no wrench or screwdriver needed. How convenient is that?
You might also hear it called a Plastic handle screw, Hand knob screws, or more specifically, a Star hand knob tightening screw. When it’s paired with a bolt, we call it a Hand knob bolt. No matter the name, their mission is the same: to make your work simpler and more efficient!
How Do We Craft Every Star Knob with Care?
A great little tool is always backed by a lot of thought. We pay special attention to every detail, from the manufacturing process to the raw materials, because we want to give you the very best!
What’s the Magic of “One-Piece Molding”?
Imagine we use a special “oven” to fuse the plastic handle and the metal screw together at high temperatures. This process is called “one-piece injection molding.” The benefit is that they combine seamlessly, becoming one solid, sturdy piece. You’ll never have to worry about the handle coming loose or breaking off when you’re tightening it!
Good Materials for a Great Feel
The Handle: Safe and Sound, Just Like LEGOs!
We insist on using only brand-new ABS plastic for our handles. You can think of it as the same high-quality plastic used to make LEGO bricks—it’s incredibly strong, durable, and most importantly, very safe, non-toxic, and odorless. This means you can use it anywhere with peace of mind.

The Screw: The “Tough Guy” from Big Brands
As a reliable Hand knob bolt, the screw part has to be tough! We select high-quality carbon steel or stainless steel for the job.
- For Indoor Use: We give our carbon steel screws a shiny “zinc coat” to protect them from rust.
- For Wet or Outdoor Use: We’ve got different grades of stainless steel for you! For kitchens and bathrooms, 304 stainless steel is perfect. If you’re near the coast or in a chemical plant, the super-corrosion-resistant 316 stainless steel is your best friend!
Plus, we only use screws from top brands (like Dongming/Tianbao) to ensure every single one is perfectly sized and threads smoothly. No more jamming or stripped screws!
Which One to Choose? Specs at a Glance!
Our family of Hand knob screws is quite large, so there’s definitely one that’s perfect for you!
- Size Matters: From the delicate M4 to the robust M12, we have a full range of sizes. Whether you need it for a small electronic gadget or heavy machinery, we’ve got you covered.
- Handle Size: We offer various handle diameters like 25mm, 32mm, 38mm, and 48mm. You can choose based on the size of your hand and the amount of torque you need, ensuring a comfortable grip!
- Custom Lengths: The screw length can be customized to your needs. No matter how thick your panel is, we can make it work.
How to Read the Size Label? It’s easy! For example, if the label says M6*20, it means the screw thread diameter is 6mm, and the length from the base of the handle to the tip of the screw is 20mm. Got it?

- Furniture at Home: Perfect for assembling furniture that you might take apart often, adjusting an easel, or securing a camera tripod.

A Few Tips for Using Your Star Knob
To make sure your Star knob lasts a long time and works perfectly, here are a few friendly tips:
- Be Gentle: It’s designed for hand-tightening, so a good firm twist with your hand is all it needs. Please don’t use a wrench or other tools to overtighten it, as that could damage the handle or the threads.
- Not a Fan of Shaky Ground: If your machine vibrates a lot, it’s probably better to use a traditional screw. Because it’s hand-tightened, a Star knob might slowly loosen over time in a very shaky environment.
- Get the Right Fit: Before you buy, double-check the size you need (both the diameter and length). The wrong size won’t fit, and we don’t want that!
- Match the Material to the Mission: If you’re using it in a damp or corrosive place, remember to choose stainless steel. It will prevent rust and keep it looking great.
- A Little Oily? No Worries!If you get a carbon-steel one, you might notice it’s a bit oily. Don’t worry, that’s not dirt! It’s a special anti-rust oil we apply to protect it. You can simply wipe it off with a paper towel before use.
- Packaging and Service: Your Peace of Mind
- Packaging: We pack the screws in small plastic bags and then place them in a sturdy cardboard box. This ensures they won’t get damaged during their journey to you.
- Our Promise: We promise that every Star knob you receive is made with care, accurately sized, and from solid materials. We stand by our products!
- Customer Service: Have any questions? Just ask! Whether you need help choosing a size or have a question about usage, our friendly customer service team is here to help you out.

I live by the sea, and it’s very humid. Which Hand knob bolt should I choose?
You should definitely go for the 316 stainless steel! It has the best corrosion resistance of all our models and is perfect for high-salt, high-humidity environments like the coast. It will stay shiny and new for a very long time!
The screw I received seems just a tiny bit different in size from what was listed. Is that normal?
Yes, that’s completely normal! It’s what we call a “tolerance” in manufacturing. Just like when you buy clothes, two items of the same size might have tiny differences. Our products are all within the standard tolerance, so it won’t affect how you use it at all. No worries!
How can I accurately measure the screw size I need?
The most accurate way is to use a caliper. You’ll want to measure two things: the diameter of the threads and the length of the screw you need. If you don’t have a caliper, you can also check the old screw or the equipment’s manual for any size markings.
