Material & Production Process
These screws are made from high-quality carbon steel, which is widely used for its excellent strength-to-cost ratio. The manufacturing process involves:
Cold heading to form the screw body and head
Slot cutting to create a precise straight slot
Thread rolling for high consistency and clean finishes
Heat treatment (if required) for mechanical enhancement
Surface treatment such as zinc or black oxide plating
Final inspection and packaging
All stages are tightly controlled to ensure the best results in terms of precision, durability, and reliability.
Typical Applications and Use Cases
Slotted Pan Head Screws are commonly found in:
Electrical terminals and switchgear
Household appliances
Vintage or retro-style equipment
Sheet metal and plastic components
Wood-to-metal assembly
Decorative hardware with traditional aesthetics
The slotted drive makes them suitable for manual installation or applications where over-torquing must be avoided.
