Plastic Spacers And Dowel Pins For Every Application
Plastic spacers and dowel pins are essential parts for maintaining exact distances and ensuring reliable positioning of components. They also provide excellent electrical insulation and thermal resistance. At Bülte you will find them in high-quality nylon (polyamide), available in many lengths and diameters to meet diverse assembly requirements.
Our retaining spacers are designed with self-locking lips, preventing loss during tightening, loosening, or transport. These anti-loss spacers are especially beneficial for automated production lines and applications exposed to vibration or dynamic loads.
For demanding environments, we also manufacture plastic spacer sleeves, standoffs and dowel pins from chemical-resistant materials such as glass-fibre reinforced nylon (PA-GF), polypropylene (PP), polyethylene (PE), polyacetal (POM), PVDF, polystyrene (PS) and more. Depending on the material, operating temperatures range from approx. −40°C to +180°C, and up to +260°C with PTFE.
Applications Of Plastic Spacer Sleeves
Our plastic spacer sleeves and dowl pins are widely used in electronics, automotive, electromechanical and medical engineering. Typical applications include:
- Electrical cabinets and electronic housings: safe insulation of printed circuit boards (PCB) and covers
- Technical furniture and industrial equipment: reliable even under shocks, vibration and oscillations
- Measurement devices and sensors

What is a plastic spacer sleeve?
Plastic spacer sleeves, also known as spacers or standoffs, are cylindrical elements, often made of nylon, that keep components at a defined distance. They ensure stable assembly and reliable insulation. Non-conductive spacers made of plastic are highly popular for their light weight, easy installation and corrosion resistance.
What are the advantages of plastic spacers?
Engineering plastic spacers offer clear benefits over metal alternatives: they are electrically insulating, lightweight and resistant to moisture and chemicals. Their versatility makes them particularly suitable for electronics, electrical and mechanical engineering, as well as automotive, aerospace, and outdoor applications.
What are retaining spacers?
Unlike standard plastic spacers, retaining or anti-loss spacers feature self-locking collars or lips to hold them in place and prevent loss during assembly or transport. This feature is especially valuable in high-speed production or environments subject to vibration.
Why choose anti-loss plastic spacers?
Anti-loss or retaining plastic spacers stay securely in place even after repeated fastening cycles. Made of durable nylon, they combine high mechanical strength with low weight and superior corrosion resistance – perfect for vibrating assemblies and automated production.
Where are plastic spacers used?
Plastic spacers and spacer sleeves are common in many industries. They provide safe electrical insulation in electronics, act as lightweight standoffs in automotive applications and ensure durability in outdoor or marine environments thanks to their corrosion resistance.
