How do I Measure The Pitch of Stainless Steel Bolts?
Steps Details
1 Measuring a Bolt is to Identify the Type of Head That You Require.
2 The diameter of the bolt in millimeters
3 Length are Measured Under the Head to the End of the Shaft
4 Determine the thread pitch

Are Stainless Steel Fasteners Magnetic?
Five Classes of Stainless Steel Non/ Magnetic Crystal Structure Examples
Ferritic Magnetic BCC 405, 430, 442
Ausrenitic Nonmagnetic FCC 201, 301, 302,303, 304, 316
Marrensitic Magnetic BCT 403, 410, 416
Duplex Magnetic Combination 2205, Alloy 255
Precipitate-Hardened Magnetic Combination 17-4PH, PH 17-7
Difference Between Stainless Steel Self-Tapping Screws and Self-Drilling Screws
Analysis of SS Fastener Parts   
Stainless Steel Self-Tapping Screws
  • Self‐tapping fasteners require a pre‐drilled pilot hole
  • producing its own mating threads by forcing the metal
  • used as primary fasteners for securing a component to the substrate
  • Two Basic Forms
    • Fine pitch thread
    • Course pitch thread
SS Self-Drilling ss-screws
  • Takes away the need for pre‐drilling, taking out one operation
  • ensures that the component parts are aligned during the installation
  • Drill point needs to be of sufficient length
  • length will also have to be suitable
  • for the effective clamping range
