This U Type Clip assortment offers a practical fastening solution for various automotive and motorcycle applications. Also referred to as chimney nuts, speed clips, or plywood nuts, these components serve as threaded receivers for screws and bolts when attaching panels, fairings, and trim pieces to vehicle bodies.
Design & Function
The U shape configuration slides over the edge of a metal or plastic panel. Internal threads cut into the clip body accept a matching metric screw or bolt. When the screw is tightened, the clip compresses against the panel surface, creating a secure mechanical connection. This design proves especially useful in locations where accessing the back of the panel with a traditional nut is impossible or impractical.
Material Properties
These fasteners are constructed from stainless steel. This material provides three practical benefits for fastener applications. First, it offers sufficient strength and hardness to maintain thread engagement under load. Second, it retains the elasticity needed for the clip to flex during installation and return to its original shape. Third, stainless steel resists surface rust and corrosion when exposed to moisture, road salts, or humidity, extending the usable service life of the fastener.
Thread Size Options
This kit includes U clips in four metric thread sizes: M4, M5, M6, and M8. These dimensions represent common standards found on passenger vehicles, motorcycles, and scooters. M4 and M5 typically suit smaller trim pieces and interior panels. M6 often appears on bumper covers and splash shields. M8 generally handles larger undertrays and structural brackets. Having multiple sizes in one kit eliminates the need to measure thread pitch before ordering separate products.
Common Application Areas
Typical uses include attaching motorcycle fairings and side covers, securing scooter body panels, mounting car bumper covers, fastening fender liners and splash shields, holding underbody engine trays, installing trim strips and rocker moldings, and securing plastic grilles to metal support frames. The versatility of the U clip design makes it useful across multiple vehicle types.
Installation Guidance
To install, slide the open end of the U clip over the edge of the panel until the threaded hole aligns with the mounting point. The clip should grip the panel lightly without falling off during positioning. Insert the matching screw or bolt through the component being attached and turn clockwise into the clip threads. Tighten until secure but avoid excessive torque that could strip the threads or deform the clip. For removal, simply unscrew the bolt. The clip remains attached to the panel edge and can be reused unless visibly damaged.
