Frequently asked questions about this product (FAQ)
What is the purpose of through-hole bolts?
The use of through hole bolts is to empty the air in the space below the workpiece with threaded holes.
To ensure the vacuum environment of the vacuum equipment.
What devices and equipment are through-hole bolts mainly used on?
Through hole bolts are mainly used in vacuum devices, vacuum containers, FPD manufacturing devices, semiconductor related equipment, electron microscopes, etc.
Is there a precision requirement for the inner hole of the through-hole screw?
Due to the main purpose of this hole being for ventilation, only the hole is guaranteed to be continuous without any requirements for positional tolerances such as concentricity and verticality.
The inner diameter can only guarantee general tolerances.
Are there any other materials available?
Due to its main use in vacuum environments, the material is currently mainly stainless steel SUS304. If there are other material requirements.
The customer is considering using our company's hex socket full length specified screws.

Did you know that using the wrong set screw can cause permanent damage to delicate components? Whether you're working with polished aluminum, plastic housings, or precision assemblies, a traditional metal set screw might scratch, deform, or even crack your components.
What do medical devices, precision electronics, and high-end furniture have in common? They all require non-marring, precision fastening solutions—and nylon tip set screws are the go-to choice.Standard fasteners often cause more harm than good in delicate assemblies.
Did you know that a single fastener can determine whether your assembly lasts for years or fails within weeks? It's not always about the size or strength of the screw—it's about the application fit. In industries where surface integrity, vibration control, and precision are essential, the nylon tip set screw is often the unsung hero.
"One wrong screw can ruin your entire assembly." That's not an exaggeration—it's a reality many engineers and manufacturers face when choosing between different types of fasteners. Imagine tightening a set screw into a soft aluminum or plastic surface, only to find cracks, scratches, or permanent damage.
In many industries, fastening delicate components without causing surface damage is a constant challenge. That's where nylon tip set screws come in — a smart and reliable solution for non-marring, vibration-resistant fastening.
When you use a sliding door or open a drawer, you can feel the smooth stop and click. This comes from the ball head plunger and spring plunger inside. A high-quality ball head plunger uses strong materials like 304 stainless steel. This gives you better durability and protects against rust.
You use a plastic ball plunger to move parts gently. Material is important. POM and PA work for everyday jobs. PEEK is better for hot or tough places. Ball plungers keep electronics and molds safe. They protect soft surfaces.
Hygiene is very important in food processing. Every part, even a stainless steel ball plunger, must meet hygiene rules. Clean machines help keep food safe for people. Picking parts that resist germs and rust means you can trust your equipment for years.
You use spring ball plunger technology to get steady preload and close tolerances in your automation equipment. Spring-loaded plungers help you get exact positioning. This makes design and performance better.
Ever wondered what makes that satisfying "click" in knobs or fixtures? It’s often a spring plunger—a small part with a big job. From holding sliding doors in place to aligning machine components, spring plungers are everywhere. Choosing the wrong one can lead to loose fits or worn-out parts.
Ever wonder how machines get their parts to line up just right? That perfect fit often depends on small components like spring plungers. These parts help with positioning, clamping, and alignment in mechanical systems. But for even greater control, eccentric bushings come into play.
Ever wonder what gives that satisfying “click” in mechanical devices? It’s often thanks to a small part called a spring ball plunger. These tiny tools are powerful when used right—but easy to misuse.
Ever wondered how machines lock, click, or hold parts in place with precision? It’s often thanks to tiny tools called spring-loaded devices. Among them, spring plungers and ball plungers do the heavy lifting. But what exactly sets them apart—and why does it matter?
Ever wonder how machines lock parts perfectly into place? The secret is often a small but powerful tool called a spring plunger. These clever devices help position, lock, or release components with precision.

A spring loaded plunger is a small device with a spring inside. The spring pushes a pin or ball into place. It helps hold, lock, or position parts in equipment. People like it because it makes strong connections. It also lets you change things quickly.
The cam action indexing plunger market is getting bigger. This is because more cars, planes, and medical devices are being made. The market was worth $2.1 billion in 2023. Experts think it will grow to $3.8 billion by 2032.
You often see T-handle, L-handle, and cam lever designs when selecting an indexing plunger with handle. Each style offers a unique way to move, adjust, and lock parts securely in place. T-handle plungers are ideal for machining, positioning, and aligning components.
