Studs and Nuts
Correct Tooth Structure, Secure Connection
The thread type and dimensions used in fasteners are critically important for the safety and performance of the system.
Selecting threads that conform to project standards directly impacts assembly compatibility and sealing.
At Positive Steel, we offer the most accurate solutions for your projects with thread structures and dimension options that comply with different standards.
UNC (Coarse Thread)
This thread type is commonly used for diameters of 1 inch and below. It offers the advantage of faster assembly and high strength.
✔ Standard use
✔ Easy assembly
✔ General industrial applications
8-UN (Fixed Thread)
This is a fixed thread structure used in ASTM standards for diameters above 1 inch.
✔ Large diameter connections
✔ High strength
✔ Flange and heavy industry applications
Metric Thread (DIN / ISO)
This thread structure has a metric measurement system and is used in projects compliant with European norms.
✔ Sizes from M12 to M100
✔ Compliance with EN / DIN standards
✔ Ideal for European projects
SIZING AND CALCULATION
Dimension Tables
The length of studs and fasteners is determined according to flange thickness, gasket type, and nut dimensions.
✔ Standard compliant calculations
✔ Project-specific dimensioning
✔ Critical data for correct assembly
