3. Threaded Insert Assemblies
When the base material is soft or subject to wear, i.e., plastic or aluminum, a strong internal thread is offered by threaded inserts. Pre-installed or inserted during heat staking or molding can be accomplished on these inserts.
Common Applications:
- Plastic housings of electronics
- Parts 3D-printed
- Thin-walled or light-weight enclosures
Key Features:
- Strengthens thread, resists wear, and extends product life
- Supports repeated assembly/disassembly without degrading base material
- Optimum application for embedded or over-molded mounting and guaranteeing structural dependability
4. Stud Assemblies
A stud is a rod having thread on both ends. One end is located inside the base material (e.g., engine block), and the other fits into a nut. This is the most applicable design where repeated dismounting has to be done without weakening the threaded base.
Common Applications:
- Diesel engine cylinder heads
- Pressure vessels, heat exchangers
- Industrial pipeline flanges
Key Features:
- Reduces wear on the base material, retaining its structural integrity
- Simplifies maintenance, as the nut is the sole part to be removed
- Functions in high-temperature and high-pressure applications
5. Self-Tapping & Self-Drilling Screw Assemblies
Cutting their own thread when screwed into the material, no pre-drilling required in most applications. They are typically used in sheet metal, wood, and lightweight framing.
Common Applications:
- Metal roof systems
- Light steel framing
- Wood furniture and cabinets
Key Features:
- Fast and quick installation, saving a huge amount of labor time
- Less tools and equipment cost, as fewer are utilized
- Best suited for rapid construction or high-speed manufacturing operations
