- Deck Fastener With Reverse Threads Prevents Back-Out
Reverse threaded sections on the shank ream wood openings to counter back-out from freezing cycles.
- Lever Shaft Assembly Form-Locking Groove and Retaining Ring
A lever shaft assembly uses a circumferential groove and projecting wall for positive rotational locking.
- Two-Piece Golf Weight Screw Retaining Ring Mechanism
A two-piece golf weight screw uses a retaining ring to secure the drive part within a cavity for reliable wrench attachment.
- Screed Assembly Compression Bolt Heating Element
Spring-loaded compression bolts maintain uniform heat distribution across asphalt paving screed plates without complex fluid systems.
- Aircraft Fuse Pin Asymmetry Prevents Misinstallation
Asymmetric head shapes and grooves on shear pins prevent misinstallation, ensuring correct load ratings during hard landings.
- Self-Tapping Screw Anchoring System for Tension-Free Mounting
Universal mounting kit prevents warping on hollow chambers by adapting screw engagement to substrate type without multiple systems.
- Hole Expanding Screw With Debris Channels
Staggered hole expanding blocks and debris exhaust channels reduce screwing torque and prevent workpiece cracking during fastening.
