Stainless Steel Hardened Type (440C or 420 Stainless Steel) may be discolored by hardening.
*1. Surface treatment for included nuts STBC is Trivalent Chromate.
*[ H ] Hardness: Hardened Tip
Feature 1: The workpiece can be adjusted slightly by adjusting the screws to achieve precise positioning.
Feature 2: Due to the implementation of high-frequency quenching at the front end (around HRC50), the wear caused by contact with the workpiece is reduced.
Feature 3: Due to the circular head shape (SR) of the front end in point contact with the workpiece, unlike flat end bolts, it can absorb the inclination of threaded holes.
Feature 4: There are two options for pitch: coarse teeth and fine teeth. When minor adjustments are required, please select fine teeth.
Feature 5: Comes with a nut for fixing screws. Therefore, after ordering the adjustment screw component, it can be fixed.

Frequently asked questions about this product (FAQ)
1. What is the specific purpose of adjusting screws?
Mainly used for adjusting the position of workpieces.
2. What are the types of adjustment screw products available?
According to different tightening methods, it can be mainly divided into various types such as hexagonal hole type, wrench groove type, hexagonal hole wrench groove type, and hexagonal bolt type.
3. Are the nuts for adjusting the screws included or do they need to be purchased separately?
It comes with 1 nut and does not require additional purchase.
4. Is there hardness in the threaded part?
Only quenching treatment is carried out on the front end, so only hardness is ensured for the shape of the front end round head, and there is no hardness for the threaded part.
Specifying fastening hardware in load-bearing environments carries incredibly high stakes. Mechanical failure is simply not an option. You rely on these components to hold massive structures and critical machinery together under immense stress.
Specify the wrong dimensions for a push button locking pin, and the assembly either fails to lock entirely or suffers from excessive axial play. This loose tolerance accelerates mechanical wear. The most common point of failure in procurement involves confusing "overall length" and "grip length."
Exacting engineering environments leave absolutely no room for guesswork. A fraction of a millimeter often determines whether an assembly holds under immense pressure or fails catastrophically.
In mission-critical applications—from aerospace rigging to medical structural supports—the failure of a quick-release fastener is not just a maintenance nuisance. It is a system-level vulnerability. Engineers often over-index on static shear strength when evaluating these components.
Industrial engineers often face a frustrating terminology paradox. You might hear procurement teams use hardware terms loosely. They ask for ball lock pins today. They ask for push button pins tomorrow. They assume these represent completely different fastening systems.
In precision industrial environments, every second of assembly time counts. Engineers require reliable, tool-less fastening solutions. You need components built for speed and absolute security. The push button locking pin meets this demand perfectly.
Manual fastening in high-vibration or load-bearing environments often forces a difficult engineering trade-off. Technicians must usually choose between maximum physical security and rapid operational speed. Traditional threaded fasteners require tedious manual tightening.
A push button locking pin acts as a critical failure point in high-load, fast-assembly environments. From aerospace assemblies and line array audio systems to heavy lifting and industrial Lockout/Tagout (LOTO) protocols, these small components carry massive operational stakes.
Push button locking pins appear as incredibly simple, reliable mechanisms at first glance. Yet, specifying the wrong pin compromises structural integrity, operator safety, and overall application efficiency. Even a minor oversight can lead to catastrophic system failure.
Selecting the exact right positive locking mechanism demands a rigorous balance. Engineers must weigh rapid manual actuation against sheer strength and environmental resilience. For decision-makers, the stakes remain incredibly high.
A push button locking pin is often a low-cost component. Yet, it frequently secures high-value industrial assets. Sizing errors carry severe operational consequences. They lead to excessive machine downtime. They cause mechanical binding during daily assembly.
Engineers constantly seek efficient ways to secure moving parts in complex assemblies. A push-pull spring plunger serves as a critical mechanical component for indexing, positioning, and locking these mechanisms seamlessly.
Engineers often drop a detent pin into a design blindly. You might expect it to handle whatever mechanical forces come its way. However, this assumption introduces severe mechanical risks.
Designing mechanical assemblies often hinges on a single, vital interaction point. You must perfectly match a spring plunger to its mating surface. This tiny engagement zone dictates the tactile feel and reliability of the entire mechanism.
Manufacturing thrives on absolute precision and repeatable actions. Engineers constantly seek reliable mechanical components designed to apply accurate, repeatable spring end-forces in tooling, fixtures, and automated machinery.
Repeatable precision in manufacturing, tooling, and product assembly depends heavily on minor mechanical components. They must function reliably over thousands of continuous cycles to prevent production halts.
In precision machinery and industrial applications, choosing the right mechanical locking or positioning component is critical for reliability, safety, and efficiency. Two common devices used for positioning and locking are indexing plungers and ball lock pins.
Indexing plungers are vital mechanical components used to secure, position, and lock movable parts in machinery, fixtures, jigs, and industrial equipment.
Custom indexing plungers are essential components in specialized machinery, industrial equipment, and precision assemblies.
Indexing plungers are essential mechanical components used across various industries to ensure precise positioning, secure locking, and repeatable alignment in machinery, fixtures, jigs, and other adjustable assemblies.
