Aluminum Body, Steel Mandrel Balancing Lightweight and High Shear Strength

MULTI-GRIP BLIND RIVET

The Multi-Grip Rivet typically consists of an aluminum alloy body and a high-strength steel mandrel. The aluminum body offers good lightweight properties and corrosion resistance, while the steel mandrel ensures high pull-force during riveting and high shear strength for the final joint. This aluminum-steel material combination provides a highly cost-effective blind fastening solution while maintaining high performance.

Cold Press Installation Clean Fastening Without Heat Impact

TSC 7 SELF-CLINCHING STANDOFFS

Unlike traditional weld studs, the TSC 7 Standoff is installed using cold press technology. The process generates no heat, completely avoiding thermal distortion or surface coating damage that welding might cause. This clean, quick fastening method is particularly suitable for pre-finished panels that have been plated or painted, ensuring the panel maintains its original aesthetic and anti-corrosion properties after the fastener is set.

Anchor Choice Friction Lock vs. Form-Fitted Lock

EXPANSION ANCHOR

UNDERCUT ANCHOR

 

The key to anchor selection lies in stress management and load requirements. The Expansion Anchor relies on friction and radial stress for fixation, making it unsuitable near edges or in cracked concrete. The Undercut Anchor relies on a form-fitted lock with no expansion stress, offering superior reliability and safety, especially in cracked concrete. The former suits g

 

Pressure Insertion Cornerstone of Anti-Torque and Structural Stability

TSC 4 SELF-CLINCHING NUTS

The TSC 4 Blind Standoff utilizes Self-Clinching technology, using intense pressure to embed its base serrations or annular ring into the thin sheet metal. This cold-working process forms a permanent, robust mechanical lock within the parent material, providing exceptionally high resistance to torque and shear strength. It ensures the standoff will not loosen or rotate, even under vibration or frequent disassembly/assembly, maintaining the structural reliability of the assembly.

Precision Alignment Facilitating Bridge Alignment for Multi-Unit Restorations

Patch Insert - 180°

The directional characteristic of the 180° Anti-Rotation Sleeve makes it crucial in multi-unit or bridge restorations. When multiple implants are used, the precise 180° orientation helps the technician and dentist to easily align all abutments, ensuring the overlying bridge or full denture can be seamlessly and stress-free installed. This simplified alignment process reduces assembly errors and guarantees the passive fit of the final restoration.

Protecting Base Material Reducing the Risk of Deformation and Cracking

 

HALF-HEXAGON RIVET NUT

HBM & HBI SERIES
HALF-HEXAGON WITH BIG FLANGE RIVET NUT FLAT HEAD,ROUND INTERNAL HOLE,OPEN END

 

When installing fasteners into soft materials (such as plastic, fiberboard, or thin aluminum), concentrated pressure can easily cause material deformation or cracking. The Large Flange semi-hex rivet nut design disperses the pulling force more evenly by increasing the contact area, thereby reducing the risk of damage to the parent material. Combined with the anti-torque property of the semi-hex shape, it effectively protects the structural integrity while ensuring a secure connection.

SPLINED RIVET NUT

SMALL FLANGE, SPLINED RIVET NUT
TSSS SERIES

The Small Flange Straight Knurl Rivet Nut (TSSS Small Flange) is an ideal choice for applications that require a balance between connection strength and surface flushness. Its straight knurling provides sufficient resistance to torque, preventing the rivet nut from spinning during tightening or subsequent use. Concurrently, the small head barely protrudes from the panel surface after installation, maintaining the flatness of the sheet metal assembly, suitable for electronic products or enclosures requiring a clean appearance and lightweight structure.

Precision and Reliability Stable Stroke and Powerful Setting

AIR PULL SETTER

The advantage of the Air Pull Setter lies in its precise stroke control, ensuring that every rivet nut installation achieves consistent clamping force and deformation—a quality difficult to match with manual tools. High-quality pneumatic components guarantee the tool's long-term durability and stable performance, reducing maintenance costs. Capable of easily handling rivet nut sizes from M3 to M10, it is the ideal choice for fastening operations that demand high quality and repeatability.

Stability Assurance Precise Clamping and Anti-Tamper Design

 

ARCHITECTURAL SEX BOLTS

Architectural Sex Bolts achieve precise clamping across various panel thicknesses by selecting different barrel lengths. This ensures the stability of the fastening between panels while avoiding over-compression. Furthermore, many bolts feature slotless (or single-slotted) head designs that, combined with their two-sided fastening, offer high anti-vandalism and anti-theft properties, making them ideal for public areas and external structures.

BAI-C Straight Knurl Sealing Non-Spinning During Tightening

BLIND RIVET NUT-WATERPROOF

FLAT HEAD RIVET, CLOSED END
BEM-C, BAI-C SERIES

 

The Large Flange Straight Knurl Sealing Rivet Nut (BAI-C) adds straight knurling to the foundation of the large flange's high bearing capacity. The straight knurls provide additional resistance to torque, preventing the rivet nut from spinning out during bolt tightening, which is vital for protecting the integrity of the sealant layer. This structure ensures the fastener maintains its waterproof performance even when subjected to heavy loads and torque, making it ideal for demanding outdoor, automotive, or industrial applications.

Pre-Set Stud Simplifying the Final Product Assembly Process

BOLT (SCREW) RIVET NUT
IN ISO DIMENSION (MM)

The greatest advantage of the Bolt Rivet Nut is its pre-fixed stud. This eliminates the step of manually aligning screw holes and bolts during final product assembly; parts are simply placed over the stud and secured with a nut. It ensures precise thread alignment, significantly speeding up final assembly while offering high pull-out and torque resistance performance. It is suitable for applications requiring exposed threads, such as car body accessories and electronic racks.

HIGHT SHEAR STRENGTH BLIND RIVET

 

 

 

MATERIAL AVALIABLE: 
RIVET: STEEL
SHAFT: STEEL
The key advantage of the High Shear Strength Rivet is its mechanical mandrel locking technology. After installation, a section of the mandrel is permanently locked inside the sleeve, eliminating the hollow center typical of standard rivets after the break. This solid sleeve design provides greater structural integrity and significantly enhances the connection's shear capacity and resistance to vibratory loosening, ensuring long-term reliability and safety.

Optimized Design Stress Distribution and Thread Fatigue Life

CYLINDER SCREW

  Many Cylinder Screws utilize special thread designs, such as larger lead-in chamfers or rolled threads, to optimize stress distribution and improve fatigue life. They are often designed as stretch bolts to maintain consistent clamping force through thermal expansion and contraction cycles. The material and length are precisely calculated to maximize resistance to high-cycle fatigue, ensuring engine reliability over hundreds of thousands of cycles.

 

Medical-Grade Material Precision Tolerance and Biocompatibility

Patch Insert - 360°

The Anti-Rotation Sleeve is precision-machined, typically from medical-grade titanium alloy or stainless steel, which are biocompatible materials. Dental applications demand extremely tight tolerances, and the sleeve must be manufactured to micron-level precision to ensure a perfect, seamless fit with the implant system. This precise fit effectively transmits occlusal forces and reduces gaps, thereby lowering the risk of bacterial ingress and surrounding tissue inflammation, which is vital for patient oral health.

Powerful Lock Extremely High Resistance to Torque and Pull-Out

TSC 6 SELF-CLINCHING STUDS

The greatest advantage of the TSC 6 Self-Clinching Stud is the strong mechanical lock created after pressing. This lock provides extremely high resistance to torque and pull-out strength, ensuring the stud does not rotate or dislodge when tightening the nut or subjected to external tensile force. This allows the connection points of the sheet metal structure to withstand heavy loads and high vibration, significantly improving the structural reliability of the entire assembly.
