300 Series Button Socket Cap Screw Characteristics 

It’s a cap screw with a cylindrical head and hexagonal drive hole. Unless specified, the screw head is clean and has no stamping or marking. The result is a smooth, finished look.

Button socket cap screws secure the mating parts or panels of an assembly or upper-level tool. An Allen wrench or hex key drives the screw into the components’ holes, and tightening occurs by applying torque to the screw head. Exact performance characteristics vary by grade, but common traits include: 

  • Very Durable
  • Avoids Rust
  • Long-Lasting
  • Easily Machinable
  • Sanitary
  • High Tensile Strength

300 series stainless steels have a long cycle life and are 100 percent recyclable, making them environmentally friendly. They’re perfect for manufacturers moving toward or aiming to highlight sustainable practices.
