Product Categories
Direct Screw Fixings for Plastics & Light Alloys
Our PT screw series and related designs allow fast, reliable installation directly into plastics and light alloys without the need for pre-tapped holes. They provide strong resistance to pull-out forces while reducing assembly time.
Inserts for Plastics
From ultrasonic and heat-installed inserts to press-in and self-tapping versions, these components create durable, reusable threads in plastic parts. They improve torque resistance, wear life, and reliability for high-performance plastic assemblies.
Fasteners for Special Materials
These include precision hardened inserts, studs, and screw-serts designed for composites, laminates, and other difficult substrates. They provide secure fastening while preserving material integrity under high stress.
Sheet Metal Fasteners
Our self-clinching nuts, studs, rivet bushes, and stand-offs are engineered to embed securely in sheet metal, creating permanent threads without welding or complex machining. They deliver strong, vibration-resistant performance with minimal space requirements.
Spring Steel & Plastic Fasteners
Our PT screw series and related designs allow fast, reliable installation directly into plastics and light alloys without the need for pre-tapped holes. They provide strong resistance to pull-out forces while reducing assembly time.
Threaded Spacers & Support Pillars
Available in hexagonal, round, and insulating types, spacers and pillars ensure precise component separation, stability, and alignment in electronic and mechanical assemblies. They are essential for PCBs and multi-level builds.
Thread Locking & Sealing
Our Nyseal and Nyplas products, along with other pre-applied sealants and adhesives, prevent loosening and protect against leakage, vibration, and environmental exposure. These solutions improve assembly reliability and reduce maintenance.
Compression Limiters & Captive Bolt Assemblies
Compression limiters protect plastic parts from over-tightening, while captive bolt assemblies ensure that fasteners remain in place even when loosened, improving safety and assembly efficiency.
Custom Manufacturer
For unique applications, PSM provides custom-engineered fastening solutions. Our team collaborates with customers to design, test, and manufacture tailored products that meet specific technical and commercial requirements.
Frequently Asked Questions
What makes specialized fasteners different from standard ones?
Specialized fasteners are designed for specific substrates such as plastics, sheet metal, or composites, and are optimized for strength, reliability, and assembly efficiency. Unlike standard screws or bolts, they solve unique engineering challenges by ensuring secure joints that resist vibration, wear, and environmental stress.
Which industries benefit most from PSM’s solutions?
PSM’s specialized fastening solutions are widely used in automotive, aerospace, electronics, telecommunications, and consumer products. These industries rely on precision-engineered fasteners to ensure structural integrity, reduce assembly costs, and maintain performance under demanding operating conditions.
How can I choose the right fastener?
Selecting the correct fastener starts with identifying the substrate material, the installation method, and the required performance characteristics such as torque or pull-out strength. Consulting PSM’s technical datasheets or working with our Application Engineers ensures you select the most suitable specialized fastening solution for your project.
Are fasteners and screws the same thing?
No, screws are one type of fastener, but not all fasteners are screws. Fasteners include a broad range of components such as bolts, nuts, washers, rivets, inserts, and spacers. While screws create or engage threads to hold materials together, specialized fasteners provide additional options for joining, locking, sealing, and supporting assemblies.
What is the difference between screws, studs, and standoffs?
Screws are threaded fasteners that cut or engage threads in materials for secure joints. Studs are threaded rods, often with threads on both ends, used to join components with nuts or tapped holes, providing strong load-bearing connections. Standoffs, sometimes called threaded spacers, maintain a fixed distance between components — commonly in electronics — to ensure alignment, insulation, and structural support.
How to Specify
Identify the application substrate (e.g. hard thermoplastic, metal sheet, PCB).
Choose installation method (ultrasonic, heat, press-in, clinch, self-tap).
Select performance criteria (torque, pull-out strength, reusability).
Consult technical datasheets or PSM’s Application Engineers for tailored advice.
