T-Shaped Toothed Bolt With Anti-Slip Design

Product introduction

The T-shaped toothed bolt is a special fastener designed for fast and firm locking in T-slots, dovetail grooves and other mechanical guide rails. It combines efficient positioning and strong locking, and is a core component in the fields of machine tools, molds and tooling fixtures. The head of the bolt has a unique T-shaped structure, which can be accurately embedded in the T-shaped groove of the equipment workbench and can easily slide in the groove to achieve stepless adjustment and rapid positioning. Its core feature is that the bottom or side of the T head is designed with precision-machined saw teeth (or knurled teeth). When the nut is tightened, these serrations bite forcefully into the groove wall or fixture base, creating a strong mechanical interlock that effectively prevents the bolt from moving or rotating in any direction when under load. This design achieves the perfect combination of rapid positioning and rigid locking, greatly improving the adjustment efficiency and overall stability of the clamp. Therefore, T-shaped toothed bolts are widely used in machining centers, milling machines, grinders and other equipment to accurately fix workpieces, molds and fixtures. They are indispensable and efficient locking components in modern precision manufacturing.

 

Product features

1. Excellent anti-rotation and anti-shift capabilities

This is its most core feature. The bottom or side of the T-shaped head of the bolt is designed with precision serrations (or knurled teeth). When the nut is tightened, these serrations will bite into the T-slot wall or the base surface of the fixture to form a strong mechanical interlock, which fundamentally prevents the bolt from rotating or moving horizontally when it is under load, ensuring absolute accuracy in positioning.

 

2. Fast sliding and precise positioning

The T-shaped head matches the T-shaped groove of the equipment workbench. During installation, you only need to put the bolt head into the groove, and it can easily slide along the groove to achieve fast and stepless displacement adjustment. This greatly simplifies the positioning process of the fixture and workpiece and improves clamping efficiency.

 

3. Extremely high clamping rigidity and stability

Once tightened, the bite effect of the saw teeth and the T-slot can withstand forces from all directions (including vertical pulling force, lateral shear force and torsion force), providing the entire tooling system with extremely high rigidity and stability, especially suitable for use in heavy cutting and high-vibration processing environments.

 

4. Easy installation and strong reliability

Its "put-slide-lock" installation process is very simple. Compared with traditional methods, it does not require additional anti-rotation devices or complex positioning steps, and at the same time avoids the risk of loosening that may occur due to the use of ordinary T-bolts, significantly improving safety and reliability.

 

Product application

1. Machine tool workbench and machining center

Application scenario: This is the most classic application field. It is used to fix workpieces, precision vises, dividing heads or other special fixtures on T-slot workbenches of milling machines, machining centers, grinders and other equipment. Advantages: The bolt can slide easily in the groove to achieve rapid positioning; when tightening, the saw teeth bite the groove wall, providing extremely high anti-rotation and shear resistance, ensuring that the fixture and workpiece remain motionless during powerful cutting processes.

 

2. Mold installation and fixation

Application scenarios: Used to quickly install and lock large molds on stamping machines, injection molding machines, die-casting machines and other equipment. Advantages: It can withstand the huge weight of the mold and the strong vibration and impact generated during work. Its anti-loosening properties are key to ensuring production safety and preventing mold displacement from causing product defects or equipment accidents.

 

3. Welding tooling and combined fixtures

Application scenario: On large welding platforms (such as welding positioners and platform tooling), it is used to position and compress the parts to be welded. Advantages: The position can be quickly adjusted to adapt to weldments of different sizes, and the locking force can be maintained under welding thermal deformation and vibration to ensure welding accuracy.

 

4. Inspection and assembly platform

Application scenarios: Used to fix the workpiece to be measured or assembly parts in situations where high-precision positioning is required, such as coordinate measuring machines and large assembly platforms. Advantages: Provide a stable, shaking-free reference fixed point to ensure the accuracy of measurement or assembly.

 

FAQ

Q: What are the core advantages of T-type toothed bolts?

A: Its core advantage is its excellent anti-rotation and anti-shift capabilities. The serrations at the bottom of the T head bite into the surface of the T-shaped groove during locking, forming a mechanical interlock. This fundamentally solves the problem that ordinary T-shaped bolts are easy to rotate or shift in the groove when stressed, and provides extremely high clamping rigidity and stability.

 

Q: What is the difference between it and ordinary T-bolts?

A: The main difference is whether the T-shaped head has teeth. Ordinary T-bolts: The heads are smooth and rely on friction to prevent rotation. They are prone to loosening when subjected to large loads or vibrations. T-type toothed bolt: The head is toothed, relying on the mechanical bite force of the saw teeth to prevent rotation, and the locking reliability is far superior to the former. It is a high-performance replacement for ordinary T-bolts.

 

Q: Can this bolt be reused?

A: Yes, but please check carefully. After repeated use, the sharpness of its serrations may decrease from multiple bites. After each disassembly, the saw teeth should be inspected for serious wear, deformation or chipping. If the saw teeth are obviously blunted, their anti-rotation effect will be greatly reduced. It is recommended to replace the bolts with new ones to ensure safety.
