Installation is straightforward — drill, tap, insert the threaded insert, then drive in the keys — with no need for chemical thread lockers or specialized tools.

With excellent resistance to harsh conditions such as extreme temperatures, moisture, and chemical exposure, these rivet nuts ensure long-lasting performance — ideal for protecting assemblies in challenging environments.

TOPSCREW’s reusable binding posts offer both utility and aesthetic appeal, securing materials firmly while allowing easy disassembly and reconfiguration to support creative flexibility.

TOPSCREW’s custom bolts are designed with precision to tailor every parameter to application needs, ensuring perfect fit with structural components while boosting fastening performance and reducing installation errors.

TOPSCREW’s versatile wood screws are engineered with threads designed specifically for wood, allowing secure penetration into both softwood and hardwood while improving joint strength and reducing the risk of splitting or loosening.

TOPSCREW’s precision-engineered spokes and nipples ensure proper tension and balanced stress distribution to help prevent wheel deformation and loosening during demanding riding conditions.

Lock pins serve as crucial fastening elements for securing and positioning structural components, ensuring that scaffolding and support systems remain stable under vibration or load. This creates a more secure working platform for personnel on site.

TOPSCREW offers anti-theft fastening solutions such as breakaway screws and one-way bolts that create irreversible lock conditions after installation, making removal with standard tools extremely difficult.

TOPSCREW’s high-shear rivets are engineered specifically for these high-stress conditions, offering shear strength up to twice that of standard rivets and maintaining secure connections even under intense shear forces.

TOPSCREW’s integrated thread-locking technology utilizes a specially optimized insertion method to increase contact area and locking depth, enabling connection points in thin sheets to withstand high loads without loosening.

TOPSCREW self-tapping inserts utilize precision-engineered cutting flutes that allow fast installation into a wide range of base materials. High-strength threaded connections can be achieved without additional tapping processes, significantly improving assembly efficiency.

The key-locking internal/external threaded insert uses a pin-engaged mechanical lock that prevents rotation and pull-out, delivering enhanced vibrational resistance and connection strength.

Vented screws eliminate these air pockets through a hollow or slotted design, ensuring rapid air evacuation and improved vacuum system performance

Blind rivets allow for quick and reliable fastening from one side, even where access to the backside is not possible — a major advantage for modern assembly environments. They provide strong clamping force, excellent joint stability, and faster installation

In modern assembly and manufacturing processes, combination screws (SEMS screws) redefine efficiency by integrating pre-assembled washers with the screw body. This eliminates the need for manual washer placement — saving time, reducing errors, and improving workflow.

Tri-Fold Rivets solve this with a unique three-pronged expansion that forms a wide anchoring base on the blind side, evenly spreading load and stress to prevent pull-through or material damage.

Efficient assembly shouldn’t come at the expense of sustainability. Traditional fastening methods often require multiple steps like welding and tapping, consuming valuable time and resources.

PlusNut threaded inserts are engineered to deliver reinforced anchoring in thin walls and hollow sections where traditional fastening methods struggle.

Although small, roof washers play an outsized role in safeguarding roof systems. They protect panel surfaces from damage, evenly distribute screw pressure, and help prevent loosening due to vibration or thermal cycling.

When installation space is limited or through-holes are not allowed, choosing the right thread solution is essential. Top Screw’s blind hole self-tapping inserts feature a closed-end design that prevents entry of debris and liquids, improving durability and resistance
