FAQ

Question?
What is the significance of the 'SA194 GR.16' specification?

Answer

ASTM A194 (or ASME SA194) is a standard for nuts intended for high-pressure and high-temperature service. Grade 16 specifically denotes a nut made from a quenched and tempered chromium-molybdenum-vanadium alloy steel, offering very high tensile strength and performance under extreme thermal and mechanical stress.

Question?
What is the recommended tightening torque for an M30 Grade 16 nut?

Answer

Tightening torque is highly dependent on factors like bolt grade, lubrication, and application requirements. For an M30 Grade 16 nut, a specific torque value must be calculated by an engineer based on the specific joint design. Always consult your project's technical documentation; generic values are not suitable for such critical fasteners.

Question?
Is the yellow coating just for color, or does it provide corrosion resistance?

Answer

The coating is a zinc-yellow passivation (chromate conversion coating). While it provides a distinctive color, its primary purpose is to significantly enhance the corrosion resistance of the underlying zinc plating and steel, protecting the nut from environmental damage during storage and in service.
