The difference between twist screws and ordinary screws

1. Thread design

Self Threading Metal Screws: Twist has a unique thread design, usually with a double helix shape. This design allows the twist to grip quickly and efficiently as it penetrates the material and provides better resistance to tensile strength and loosening. At the same time, it is particularly suitable for the connection of soft or brittle materials, reducing the risk of material damage.

Common Screws: Common screws are usually designed with a straight thread and are suitable for general fastening applications. Their gripping force is relatively small and depends mainly on the friction generated during tightening.

2. Applicable Materials

Self Threading Metal Screws: Due to their thread design and construction, twist screws are suitable for a wide range of materials, especially in wood and plastics, providing better fixing results.

Ordinary Screws: Ordinary screws are also suitable for wood, metal and some plastic materials, but may not be as effective as twist screws in soft materials.

3. Usage Scenarios

Self Threading Metal Screws: Suitable for occasions that require high strength and reliability, such as woodworking, furniture making and industrial machinery connection.

Ordinary Screws: Suitable for home improvement, daily maintenance or general connection, usually performs well in light and normal use situations.

Galvanized iron or stainless steel material, which one is right for me?

● Corrosion resistance:

Galvanized iron: with anti-corrosion layer, suitable for wet environment, but easy to rust in long-term use.

Stainless steel: corrosion resistance, suitable for wet and chemical environments, almost no rust.

● Strength and durability:

Galvanized iron: high strength, but average performance at high temperatures or under long-term loads.

Stainless steel: better strength and toughness, high temperature resistance, not easy to deform.

● Price:

Galvanized Iron: Inexpensive and suitable for projects with limited budgets.

Stainless steel: higher price, but more durable and more cost-effective in the long run.

● Applicable scenes:

Galvanized iron: suitable for home and indoor applications, not suitable for outdoor or humid environment.

Stainless steel: suitable for outdoor, wet or harsh environments such as marine and chemical equipment.

●Aesthetics:

Galvanized Iron: Ordinary appearance, may discolor over time.

Stainless Steel: Smooth appearance, retains luster.

Choose galvanized iron: if budget is limited and the use environment is dry.

Choose stainless steel: if corrosion resistance and long-term durability are required, for wet or harsh environments.
