ISO Self Tapping Cap Screws

A Cap Screw, sometimes referred to as a Cap Head Bolt, are a type of threaded fastener that is commonly used when making mechanical connections between mating components. The Cap Head Screws ensure the objects are held together securely.

Cap Screws have a large head and a cylindrical shaft with an external thread. The head of the plastic cap screw is hexagonal in shape; these Hex Head Screws are available as either a flat head bolt or with a slotted drive.

Our Hexagon Head Cap Screw range is lightweight and also resistant to corrosion, oil, abraision, and most chemicals.

Our Hex Screw range is available in a choice of plastic materials, including;

• Synthetic Nylon 6/6 with its has high mechanical strength and rigidity, wear resistance and damping ability
• Polyamide 6.6 that has good heat resistance, durability and strength
• Polycarbonate (PC) which is a strong, transparent plastic with great impact resistance
• Polyether Ether Ketone (PEEK) with UL rated flame resistance; a material that has a continuous use temperature of 180C, and good chemical resistance
• Polypropylene (PP), a semi-rigid thermoplastic material with good heat and fatigue resistance
• Polyvinylidene Fluoride (PVDF) with good thermal stability, UV resistance, as well as good resistance from abrasion, high energy radiation, creep, fatigue, chemicals and solvants, and has high dielectric strength.
  

Our Hex Head Screw colour options include; Black, Light Brown, Clear (Transparent), Maroon, Natural and White.

• UL94 V0 and UL94 V2 flame rated options
• DIN and ISO rated options
