With more than 20 years of experience in manufacturing, we are able to respond quickly to our customers' needs,
simplifying and precisely controlling the entire production cycle of our products.
To start, simply select a manufacturing process and upload a 3D CAD file.
Within a few hours we'll send you design for manufacturability (DFM) analysis and real-time pricing.
Once you review your quote and place your order, we'll start the manufacturing process. We also offer finishing options.
Suitable for precision electronics, electrical appliances, home furnishings, sports equipment, medical devices, child seats/ strollers/toys, automotive parts, new energy battery components, and the optoelectronics industry.
A Straight-grained double stud features straight(parallel)threads on both ends without a head in the middle.Compared with tapered or self-tapping fasteners,straight threads provide better alignment,consistent torque,and repeatable assembly.
A Passivated Bright Nickel Flat Head Hex Socket Screw is a precision fastener designed with a countersunk flat head and internal hex drive.Once installed,the head sits completely flush with the mounting surface,improving safety,appearance,and functional performance.
A Ball Head Bolt is a specialized fastener designed with a rounded or ball-shaped head that allows for secure connections while accommodating angular adjustments.Unlike standard bolts,its unique geometry ensures a smooth installation in assemblies requiring precise alignment.This makes it an ideal choice for high-performance automotive applications,machinery,and industrial equipment where both strength and flexibility are critical.
The Self-Tapping Semi-Thread Screw(ALSA1190104)is a precision fastener engineered for stable and efficient assembly in 3D printing structures.Featuring a flat head internal hex socket,partial thread design,and zinc-nickel alloy surface treatment,this screw provides excellent holding strength,corrosion resistance,and long-term reliability.
Hexagonal Studs,also known as Hex Studs or Hexagon Stud Bolts,are threaded fastening components featuring a hexagonal body that allows easy installation and removal using standard tools.
The large flat head slotted machine screw is a precision fastening component designed for applications that require a flush surface finish,stable mechanical strength,and reliable electrical performance.With a classic slotted drive and a wide flat head,this flathead slotted machine screw is especially suitable for electrical switch assemblies where appearance,conductivity,and secure fixing are critical.
A Square Step Screw,also known as a Square Stepped Screw or Square Shoulder Screw,is a precision fastener designed with a square shoulder section between the head and the threaded part.This unique step structure provides accurate positioning,strong shear resistance,and improved load distribution during assembly.
Press on Studs(also known as Press-on Stud or Press in Studs)are mechanical fasteners designed to be permanently installed into metal or sheet materials through a pressing process rather than traditional threading or welding.
Press in threaded studs,also known as press-in threaded stud or self clinching threaded studs,are permanent fastening components designed to be installed into thin metal sheets without welding or tapping.Once pressed into the base material,the stud becomes firmly locked,providing a strong and reliable internal or external thread for repeated assembly.
ress in studs for aluminum are precision fasteners designed to be mechanically pressed into aluminum or aluminum-based components,creating a strong,permanent threaded anchoring point without welding or secondary machining.
A press in stud bolt is a type of fastener that is mechanically pressed into a pre-drilled or molded hole,forming a strong,vibration-resistant connection without the need for welding,adhesives,or secondary threading operations.
Hollow rivets,also known as countersunk rivet nuts,are fastening components designed to permanently join two or more materials together while maintaining a smooth,flush surface.Unlike solid rivets
Rivet nuts are versatile threaded inserts used to create strong, reliable threads in thin metal or soft materials. Installed from one side, they are ideal for applications with limited backside access.
This hollow rivet is manufactured from high-quality SUS304 stainless steel and is designed for fastening thin materials and precision components. Compared with solid rivets, hollow rivets require less setting force while maintaining stable mechanical performance, making them ideal for modern industrial applications.
Environmentally friendly blue zinc hollow rivets are fastening components designed for secure, lightweight, and aesthetically clean assembly. Unlike solid rivets, hollow rivets feature a central cavity, allowing easier deformation during installation while maintaining excellent holding strength.
The Lock Nut,also known as a Locking Nut or Self Locking Nut,is a fastening component designed to prevent loosening caused by vibration,repeated motion,or long-term use. Product Number AJMA0420012 is an internal hexagon socket set screw manufactured from SUS304 stainless steel,featuring a 1/2-20 thread with 11.5 mm length and a passivated natural finish.
A Hex Nut,also known as a Hexagon Nut or Hexagonal Nut,is a six-sided internally threaded fastener designed to be used with bolts or threaded rods.Its hexagonal shape allows easy tightening and loosening using standard tools such as wrenches or spanners.
