Product Introduction
Bolt Screw Set STS
The use of Self-Tapping Screw Sets (STS) is primarily based on their efficiency, reliability, and economic advantages in specific application scenarios.
The following is a detailed analysis of the causes:
1. Self-Tapping Function: No pre-drilling required, saving time and costs - Direct Tapping: The tip design of self-tapping screws, such as tips, drills, or grooves, allows them to cut threads directly in materials such as metal, plastic, or wood, eliminating the need for pre-drilling or tapping. - Simplified Processes: Ideal for mass production or on-site installations, reducing tool changeovers and operational steps and improving efficiency.
2. High bond strength and loosening resistance - Thread forming: Self-tapping screws form matching threads inside the material when screwed in, providing a higher bite force than regular screws. - Anti-loosening design: Some STS kits include locking gaskets or nylon coatings (e.g., anti-loosening screws) for use in vibrating environments (e.g., automotive, mechanical).
3. Wide Material Compatibility - Metals (e.g., thin steel plates, aluminum profiles): Commonly used in sheet metal assembly, electrical cabinets, etc. - Plastics and Composites: Avoid material cracking (e.g., electronic device housings). - Wood: An alternative to traditional wood screws, especially suitable for hardwood or MDF.
4. Diversified design to meet different needs - Head type selection: round head, flat head, hex head, etc. to adapt to different installation tools (screwdriver, wrench) or aesthetic needs. - Thread Type: - Coarse Thread: Used on soft materials (e.g., plastic, wood). - Fine Threads: Suitable for metal or high-precision assembly. - Special Coating: Rust-resistant (galvanized), insulated (nylon) or corrosion-resistant (stainless steel) material.
5. Economy and Ease of Maintenance - Reduced Costs: Reduced procurement of drilling tools and additional accessories.
- Easy Replacement: If the thread is damaged, replace the slightly larger self-tapping screw or use a thread repair kit. Typical Application Scenarios
- Industrial Manufacturing: Sheet metal splicing, chassis assembly. - Architectural decoration: light steel keel, gypsum board fixing.
- Electronic and Electrical Appliances: Circuit board mounting, plastic housing fixing.
- Car maintenance: Interior parts, wiring harness fixing.
Application
For attachment of Channels and Flex Frames to profiled insulated roof sheets,
trapezoidal decking or sandwich panels with a timber batten sub-structure.
Scope of delivery
Bolt Screw incl. Sealing, Nuts and Spacers.
Installation
1. Drill a Ø 6.5 mm hole through the highest point of the roofing into the
timber battens below. Use Channel as a drilling template
2. Drill out a Ø13mm counter-bore hole through the roof material to the face
of the batten.
3. Install the Bolt Screw such that the woodscrew thread is fully engaged to
the timber in order to provide the maximum load capacity. The sealing
disk should be compressed against the batten. Insert Channel or Bolt
Screw Plate STP and tighten the self-locking flange nut (wrench size 15).
