High-Strength Alloy Steel Standard T-Screws

Product introduction

T-screws, usually referred to as T-slot bolts, are a special shape of screws. Its head is an inverted T shape and is designed to be embedded in the T-shaped slot of a machine tool table, fixture or profile. When the nut is tightened, the T-shaped head will get stuck in the groove, thereby firmly clamping the workpiece. These fastener screws are key connections in modular assembly systems.

 

Product design and features

Automatic positioning and locking: When installing, the T-shaped head can be directly placed into the T-shaped slot, slide along the slot to the desired position, and quickly locked by rotating the nut.

High load-bearing and anti-rotation: The wide T-shaped head is in contact with the groove surface, can withstand greater lateral force than traditional screws, and can effectively prevent the screw from rotating during tightening.

Compatibility: Design needs to accurately match standard T-slot dimensions (width, depth).

For fields with higher requirements, such as aerospace, non-standard screws that strictly comply with standards are used. For example, titanium T-screws that comply with EN 3308 standards have a hexagonal head, thread-to-head design, and are anodized and lubricated with molybdenum disulfide to meet extreme environmental requirements.

 

Materials and application fields

Stainless steel, excellent corrosion resistance, main application areas: food machinery, chemical equipment, medical equipment, outdoor construction

Alloy steel, high strength, high hardness, main application areas: heavy machinery and equipment, mold manufacturing, stamping machine tools

Titanium alloy, high strength, low density, corrosion resistance, high and low temperature resistance, main application areas: aerospace, high-end racing, medical implants (requires biocompatibility)

General fastener screws are widely used in various industries, while special-shaped screws (such as T-shaped screws) are more focused on areas that require fast fixtures, modular design and heavy-duty load-bearing, such as CNC machining centers, welding tooling, aluminum profile frame construction, etc.

 

Quality control and certification system

Screws in high-end or critical applications have strict quality controls, usually involving:

International/industry standards: such as EN 3308 and SAE AS4959A in the aerospace field, ISO 898 series and ASTM F606 for general mechanical properties.

Mechanical performance testing: including tensile strength, guaranteed load, wedge load, surface and core hardness, breaking torque test, etc.

Comprehensive quality control: From the chemical composition analysis of raw materials, to dimensional and appearance inspection during the production process, to performance verification before shipment, a complete chain is formed.

 

Customized services

Many manufacturers offer customization of non-standard screws. The process usually includes:

Demand confirmation: Customers provide drawings, samples or detailed working conditions.

Technical assessment: Engineers analyze materials, heat treatment, and processing feasibility.

Proofing and verification: Make samples for customer testing.

Mass production and quality control: Mass production according to confirmed standards and strict inspection.

 

FAQ

Q: How do I choose the right T-screw for my device?

A: Key parameters: 1. T-slot size (slot width and slot height) to ensure that the screw head can be placed and slid; 2. Thread specifications (such as M8, M10); 3. Material and strength level, selected based on load (mechanical stress) and environment (corrosion, high temperature); 4. Effective length, which must meet the sum of the workpiece thickness, nut, and gasket set.

 

Q: Can T-type screws with special materials or coatings be customized?

A: Yes. Professional fastener manufacturers can provide customized services, using materials such as titanium alloy and special stainless steel, and performing surface treatments such as anodizing (for titanium alloy anti-corrosion and aesthetics), galvanizing, Dacromet and other surface treatments.

 

Q: What is the difference between T-type screws and ordinary hexagonal bolts?

A: The main difference is in the head and application method. The head of the T-shaped screw is used to snap into the T-shaped slot to achieve quick positioning and anti-rotation; ordinary hexagonal bolts need to be tightened from the side of the workpiece through nuts or threaded holes. T-screws are commonly used in fixtures and modular frames, while ordinary bolts are more commonly used.
