Through-Hardened Tool Steel Screw
Manufacturer:
Rajlaxmi Industries
Origin:
Ahmedabad, Gujarat, India
Delivery:
Pan India & Global Export
Product Overview
Through-hardened tool steel screws for extreme mechanical loads, engineering polymers, and high-pressure injection molding.
Unlike surface-nitrided screws, through-hardened screws are vacuum heat-treated to achieve identical high hardness throughout the entire core and flight body. Ideal for engineering thermoplastics and optical components.
Material Grades
AISI D2, H13, DC53, SKD61, Powder Metallurgy CPM Steels
Hardness Rating
Uniform 58 - 62 HRC through the core and flights
Key Technical Advantages
- Zero risk of surface flaking or delamination
- Superior core fatigue and torsional shear strength
- Recommended for PMMA, Polycarbonate, PEEK, Ultem, and PPS
