Spring Plungers - Ball End - Smooth

Disponibile - Per maggiori informazioni visita le FAQ In produzione

These Spring Plungers with a ball end and a smooth body design are used for locating, applying pressure or lifting off. It is made of three parts: a smooth body, a ball end, and a spring mechanism. They resemble pin-end spring plungers, but the ball end engages more gently and reduces wear and tear on both the workpiece and the plunger.

The plunger's ball end provides a point of contact for accurate engagement and positioning within the application. The collar on the spring plunger serves as a retention function, keeping the plunger securely in place once inserted.

Its smooth body facilitates insertion and is held in place using an interference fit, as well as quick release. It can withstand temperatures of up to 250ºC and is widely utilised in machine and fixture design, electronics, medical, electronics, automotive, and lighting equipment.

  • Used for locating, applying pressure or lifting off.
  • Resemble pin-end spring plungers, but the ball end engages more gently and reduces wear and tear on both the workpiece and the plunger.
  • It can withstand temperatures of up to 250ºC.

Torx Head Flanged Cap Screws

Disponibile - Per maggiori informazioni visita le FAQ In produzione

These Torx Head Flanged Cap Screws are fasteners for various applications requiring a secure and durable connection. These screws combine the benefits of a Torx head screw with the help of a flanged head.

They are well-known for their exceptional grip and resistance to cam-out, making them suitable for applications requiring high torque. The flanged cap gives an extra layer of rigidity and support, making these screws perfect for situations where vibration or movement is an issue. This feature keeps the screws from becoming loose over time, guaranteeing a long-lasting and stable connection. It also spreads the screw heads weight across a broader area, preventing the screw head from sinking into the material and harming the surface.

Commonly used in industries such as automotive, machinery, and electronics. They are especially useful in situations where access is restricted. The Torx head enables efficient and dependable installation in tight places or difficult-to-reach regions.

Cap Screws - Low Head

Disponibile - Per maggiori informazioni visita le FAQ In produzione

This range of Cap Screws are available in a choice of hexagonal drive or torx drive. Hexagonal drives are ideal for precision assembly and are ideally used where less surface area is available. Torx drives provide a positive-engaging, fast-locating technique for transmitting drive torque with less necessary downward pressure. These Cap Screws are available in a choice of two low head options: ultra low head and extra low head.

The first of these options helps reduce the screws overall head height space, which means no countersinking is required, unlike flat head screws. The second option has an extremely low profile, and does not need a countersunk location hole. These screws are suitable for machine and equipment applications, with minimal clearance.

Cap Screws are commonly used with Threaded Captive Washers (sold separately).

The screws are made from austenitic Stainless Steel that provides good resistance to corrosion and machinability. The material is a popular choice for construction and automotive applications.
