Screw
A screw is a threaded fastener designed to be inserted into a material (often without a nut), forming its own mating thread.
Usage in Semi-Trailers
Common Applications
- Securing interior panels, trim, and light-duty fixtures.
- Attaching electrical components, junction boxes, and wire clamps.
- Fastening mudflaps or splash guards (when not load-bearing).
Load Bearing
- Generally non-load-bearing; used for fixtures and accessories.
Installation Method
- Driven directly into sheet metal, wood, or plastic using drills or impact drivers.
Inspection Focus
- Look for corrosion, thread stripping, and loosening due to vibration.
Failure Risk
- Stripped threads or pull-out under vibration or thermal cycling.
Replacement Considerations
- Often replaced with same-size screw; thread engagement is key.
- Ideal for non-structural repairs and quick fixes.
