Product Selection Differences for Special Purpose Fasteners

When selecting special purpose fasteners, there are several key differences to consider:

1. Material: Choose a material that suits the application requirements, such as stainless steel, carbon steel, or aluminum.

2. Coating: Consider whether the fasteners need to have a coating for corrosion resistance or other specific properties.

3. Head Style: Different head styles (e.g., hex, pan, flat) offer varying levels of strength and access.

4. Drive Type: Options include Phillips, slotted, Torx, hex, etc. Choose one based on ease of use and torque requirements.

5. Thread Type: Decide on the type of thread, such as machine screw threads, self-tapping threads, or wood screw threads, based on the material being fastened.

6. Size and Length: Ensure the fastener size and length are appropriate for the application to provide sufficient clamping force.

7. Strength Grade: Consider the strength grade of the fastener, such as ASTM grades for bolts, to ensure it meets the required load-bearing capacity.

8. Special Features: Some fasteners come with special features like locking mechanisms, anti-vibration properties, or tamper resistance.

By carefully evaluating these factors, you can select the most suitable special purpose fasteners for your specific needs.
