Selection Guide Application Differences Between Small and Large Flanges

SMALL FLANGE & FLAT HEAD BLIND RIVET NUT

SMALL FLANGE BLIND RIVET NUT, OPEN END
SEM, SAM, SAI SERIES

The choice between the Small Flange (SEM) and Large Flange (SAM/SAI) primarily depends on two key factors: the nature of the base material and the load requirements of the connection. If the base material is soft or thin, and high pull-out strength is needed, the Large Flange should be chosen to maximize the bearing surface. If the application requires a high degree of surface flushness and has general load requirements, the Small Flange is a more suitable choice. Selecting the correct flange type is the first step in ensuring the reliability of the rivet nut connection.

Optimized Stress Dispersion Sealed Connection for Soft Materials

BLIND RIVET NUT-WATERPROOF

LARGE FLANGE SPLINED RIVET NUT, CLOSED END
TSBS-C SERIES

The large flange design of the TSBS-C is particularly important when applying it to softer or composite panels. It broadly disperses stress under high loads, effectively reducing the risk of damage to the parent material. Combined with the anti-rotation property of the straight knurling, the sealant layer maintains integrity after tightening, ensuring the connection remains secure and waterproof even in high-stress, high-vibration, and moist environments.

The Optimal Choice for Square Holes Superior Anti-Rotation

SQUARE BLIND JACK NUT

★ OTHER SIZE, MATERIAL ARE AVAILABLE UPON REQUEST 
The Square Blind Jack Nut is an innovative fastener specifically designed for square pre-punched holes. Its square body provides several times greater resistance to torque than a round Jack Nut when installed into a square hole. This completely eliminates the risk of the nut spinning out during bolt tightening or removal. It is the ideal solution for hollow or soft material applications requiring high load capacity and extreme stability.

Tri-Fold Design Solving Fastening Issues in Brittle Materials

STRETCH FOLDING BLIND RIVET
( TRI FOLD BLIND RIVET )

MATERIAL AVALIABLE: 
RIVET: ALUMINUM 5050
MANDREL: ALUMINUM 5056

The key advantage of the Stretch Folding All-Aluminum Rivet is its unique tri-fold structure. During installation, the aluminum sleeve expands uniformly outwards, forming three large bearing petals. This design widely disperses the clamping stress, effectively preventing the base material from cracking or being damaged when fastening plastics, fiberglass, wood, or brittle panels. The all-aluminum construction ensures excellent corrosion resistance and lightweight characteristics.

One-Way Locking High-Security Anti-Theft Fastener

單向公母套

ONE WAY SEX BOLTS

The One Way Sex Bolt is a fastener specifically designed for permanent anti-theft locking. The head of the male or female component uses a special structure that only allows rotation in one direction (installation) with standard tools, but once fastened, it cannot be reversed (removed) with traditional tools. This one-way locking function provides the highest level of security for public fixtures, surveillance equipment, art displays, or any application requiring protection against unauthorized removal.

High-Efficiency Thread Reinforcement Ideal for High-Load Applications

SELF TAPPING THREADED INSERT
W. THREE CUTTING HOLE

Thanks to its powerful cutting ability and locking stability, the Three-Hole Self Tapping Insert is the ideal choice for thread reinforcement in high-load applications. It can quickly repair damaged or worn threads, creating a connection point that is more durable and has a higher load-bearing capacity than the original thread in the base material. Since the installation process eliminates pre-tapping, it significantly saves labor time, making it a high-performance fastening solution for improving product quality and production efficiency.

Stainless Steel Construction Durable Connection in Harsh Environments

 

ARCHITECTURAL SEX BOLTS

Given the high durability requirements of architectural applications, Architectural Sex Bolts are typically manufactured from premium stainless steel (such as 304 or 316). The stainless steel material provides excellent corrosion resistance and weatherability, allowing it to withstand prolonged exposure to outdoor, humid, or polluted environments. This material choice guarantees the long-term stability and sustained aesthetic appeal of the structural connection points.

 

Weld Studs Providing Permanent Connection with Extreme Strength

WELDING STUD

The Welding Stud is a fastener permanently welded onto the metal base material by melting the stud's base using methods like electric arc or capacitor discharge. This molten metal connection provides extremely high shear strength, tensile strength, and torque resistance, often comparable to the base material itself. It is suitable for applications demanding the highest connection strength, such as bridges, automotive structures, elevators, and heavy machinery.

Truss Combo Head Increased Bearing Surface and Generous Appearance

TRUSS COMBO HEAD POST SCREW
CHICAGO SCREW

The Truss Combo Head Post Screw is characterized by its domed, large-diameter head (Truss Head). This head style provides a larger bearing surface, helping to disperse clamping force and reduce stress on soft or fragile base materials. Concurrently, its rounded appearance is highly decorative, suitable for fastening leather goods, furniture, or display items, ensuring both connection strength and adding a generous, professional visual effect.

    

Tool-Free Boosting Efficiency in Scaffolding Erection

FRAME SCAFFOLDING FLIP LOCK PIN

 

The installation process of the Flip Lock Pin is tool-free; operators can complete the insertion and locking by hand. This significantly improves the efficiency and convenience of erecting scaffolding in confined or elevated environments. Compared to traditional nut-and-bolt systems, the flip lock design is not only faster but also reduces the risk of losing small parts. It is the standard fastener for achieving rapid erection and high-frequency use in the modern construction industry.

 

Vented Screw Solving Gas Trapping in High Vacuum Equipment

Vented screw
The Vented Screw is a special screw featuring a through-hole or venting channel along its axis. The purpose of this design is to facilitate the rapid removal of trapped gases within screw holes and beneath the screw head in high vacuum systems. In applications with extreme vacuum requirements, such as semiconductor manufacturing, aerospace technology, and high-energy physics experiments, the Vented Screw is a critical component for ensuring fast pump-down and maintaining ultra-high vacuum environments.

TSC 5 Standoffs Perfectly Flush Installation on the Backside

TSC 5 SELF-CLINCHING LOCK NUTS

The main feature of the TSC 5 Self-Clinching Standoff is its specially designed head, which allows the insert head to be completely flush with the backside of the sheet metal after installation. This is critical for electronic enclosures, sheet metal parts, or any application requiring an extremely flat and obstruction-free surface. It provides precise separation distance while ensuring maximum aesthetics and space utilization.

Flange Nuts Increasing Contact Area for Optimized Clamping Force

CYLINDER NUT

 

To enhance clamping efficiency and stability, many Cylinder Nuts utilize a Flange design. The flange increases the contact area between the nut and the cylinder head, helping to distribute stress and reduce damage to the parent material. Some nuts also feature Self-Locking functions, such as nylon inserts or distorted threads, further improving resistance to loosening in extreme vibration environments, ensuring a durable and stable connection.
