ຄວາມແຕກຕ່າງລະຫວ່າງປະເພດ 307 ແລະ 308 ແຕະໃສ່ດ້ວຍຕົນເອງ

ປະເພດ 307 Self-tapping Inserts:

1. Material and Surface Treatment: ປະເພດ 307 self-tapping inserts are typically made of carbon steel with a Parkerized surface treatment, providing additional corrosion resistance.

2. ຄໍາຮ້ອງສະຫມັກ: ປະເພດ 307 self-tapping inserts are usually used to repair or reinforce threaded holes, particularly suitable for soft metals such as aluminum or magnesium.

3. Features: They have high strength and durability, enhancing thread connections for reliable performance.

4. Specifications: The specifications and sizes of Type 307 self-tapping inserts vary according to requirements, typically suitable for specific hole sizes.

ປະເພດ 308 Self-tapping Inserts:

1. Material and Surface Treatment: ປະເພດ 308 self-tapping inserts are typically made of stainless steel (such as 303 ສະແຕນເລດ) and undergo passivation treatment to improve corrosion resistance.

2. ຄໍາຮ້ອງສະຫມັກ: ປະເພດ 308 self-tapping inserts are usually used to repair or reinforce threads and are used in environments where higher corrosion resistance is required.

3. Features: They have similar functionality to Type 307 inserts, but due to the use of stainless steel materials, they are more suitable for use in environments requiring corrosion resistance.

4. Specifications: The specifications and sizes of Type 308 self-tapping inserts also vary according to requirements, typically suitable for specific hole sizes.

The main differences between Type 307 and Type 308 self-tapping inserts lie in the material and surface treatment, as well as differences in their application environments and specific purposes.
