M18 x 100mm Hex Set Screw | DIN 933 | A4-70 Stainless Steel

The M18 x 100mm size gives this Hex Set Screw a useful fixing profile for fabricated steel brackets, with a hex head that can be tightened using conventional workshop tooling.

The A4-70 stainless steel grade is selected for outdoor, marine and washdown environments where resistance to corrosion is a key requirement. The M18 thread size makes it easy to match against compatible nuts, washers and tapped components without changing the installation method.

Common Applications

  • External plant, chemical handling areas and marine-grade maintenance work
  • Retail display frames, commercial furniture and modular support rails
  • Temporary fixtures, prototypes and adjustable mechanical test builds

Why Choose This Fully Threaded Hex Screw?

  • 2.5mm pitch provides predictable thread compatibility across standard metric components
  • 11.9mm head height helps with clearance planning during equipment design
  • A4 stainless steel hex set screw wording gives this SKU a clear use case within the broader DIN 933 set screw range
