Key Features:

Material: Premium 1022A carbon steel for exceptional structural integrity and load-bearing capacity.

Dimensions: Thread size M6/M8 × Length range 38mm–70mm (suitable for medium-duty applications).

Coating: Zinc-plated finish with optional salt spray resistance ratings of 500H, 1000H, or 1500H, meeting Class 3/Class 4 standards for enhanced corrosion protection in demanding conditions.

Hardness:

Core Hardness: 380–440 HV (balanced for ductility and fracture resistance).

Surface Hardness: 620–720 HV (high-frequency hardened to ensure durability during drilling and fastening).

Design:

Countersunk Head: Flush installation for a smooth, tamper-resistant surface.

Internal Torx Drive: Tamper-proof, high-torque compatibility for secure fastening.

Flange & Self-Drilling Tip: Integrated flange distributes clamping force evenly, while the drill tip eliminates pre-drilling in metal, wood, or composite materials.

Applications: Perfect for automotive assembly, machinery, electrical enclosures, and structural frameworks requiring precision fastening, corrosion resistance, and a low-profile finish.
