Button Screws

An internal hexagonal round head screw, also known as a pan head internal hexagonal screw, has a circular arc-shaped head, which is beautiful and evenly stressed. It is a commonly used fastening connector in industrial and daily assembly.

Common materials
-Carbon steel: High cost performance, moderate strength, mostly used for fixing the shells of ordinary equipment, furniture, and electrical appliances.
-Stainless steel 304: rust-proof, corrosion-resistant, suitable for humid, outdoor, food machinery, medical equipment, and other environments.
-Stainless steel 316: With stronger acid and alkali resistance and salt spray resistance, it is commonly used in maritime, chemical, and high-end equipment.
Strength grade
-Grade 4.8: Made of low-carbon steel with low hardness, used for light loads and non-critical parts.
-Grade 8.8: Medium carbon steel, after heat treatment, has high strength and is the most widely used.
-Grade 10.9/12.9: High-strength alloy steel, used for molds, mechanical transmissions, automobiles, and heavy-duty equipment.

Application scenarios
Hexagonal socket head screws are widely used for:
-Home appliances, digital products, and instrument casings
-Furniture, cabinets, fitness equipment, children's toys
-Automation equipment, medical devices, rail transit
-Precision assembly scenarios with high requirements for appearance and limited space
It is easy to install and has stable torque, which not only meets the fastening requirements but also enhances the overall texture of the product.
