Plastic Materials for High-Strength Fasteners & Production Methods

October 19, 2026|Material|

Why plastic fasteners at all Plastic fasteners are chosen over metal when applications need electrical insulation, corrosion resistance, weight reduction, chemical resistance, non-magnetic properties, or cost savings at high volumes. “High-strength” in plastics is relative [...]

Fastener Microstructure Analysis via Metallography

October 18, 2026|Quality|

Metallography — the microscopic examination of a material’s internal structure — is one of the most direct ways to verify that a fastener’s heat treatment actually produced the microstructure its strength grade depends on. For [...]

Pitch Diameter, Major/Minor Diameter & Tolerance Classes

1. The Three Controlling Diameters Every screw thread is defined by three diameters, and each plays a different role in whether a thread assembles and functions correctly: DiameterExternal thread (bolt)Internal thread (nut)MajorOutside diameter of the [...]

Thread Gauging Methods: A Comparison

October 18, 2026|Quality|

Screw thread acceptance can be checked three fundamentally different ways — by functional pass/fail attribute gauging, by optical profile comparison, or by full dimensional/geometric measurement on a CMM. Each answers a different question, and most [...]
