Why Choose Us

AS3566 Australian Standard Compliance

BHD Fasteners are manufactured in strict accordance with AS3566, the Australian standard governing
self-drilling and self-tapping screws. This ensures dimensional accuracy, mechanical performance,
and corrosion resistance that meets global benchmarks. Every batch undergoes pre-production
assessment, machining inspection, heat treatment validation, and final verification.

25+ Year Corrosion Resistance

Our fasteners feature advanced Ruspert coating, a high-performance surface treatment designed to
withstand extreme environmental conditions. Tested through 1000-hour salt spray tests and
Kesternich cycle evaluations by TUV SUD, Ruspert coating delivers proven rust protection for over 25
years, even in coastal and industrial atmospheres.

Superior Water Leakage Protection

Water ingress is a primary cause of premature roof and cladding failure. BHD fasteners incorporate
premium EPDM (Ethylene Propylene Diene Monomer) washers that maintain elasticity and sealing
integrity over decades. The washer's large bearing surface and chemical resistance ensure reliable
waterproofing under thermal cycling, UV exposure, and mechanical stress.

Precision Engineering for Ease of Installation

• BHD fasteners are designed with precision drill points and optimized thread geometries that reduce
• installation effort and improve pullout performance. Features include:
• Non-walking points for fast material engagement
• Point-to-thread design that minimizes backout
• High threads under the head to prevent panel strip-out
• Cutting edges that enhance drill performance with less torque

Global Certification and Testing

Quality assurance is built into every stage of production:
SGS Certification: Independent verification of material composition and mechanical
properties
TUV SUD Testing: Batch-wise coating quality checks, including salt spray and corrosion cycle
tests
AS3566 Compliance: Adherence to dimensional, performance, and coating standards


Reliability in Indian Conditions
India's diverse climate zones – from humid coastal regions to arid inland areas – demand fasteners
that perform consistently. BHD's proven corrosion resistance, waterproofing capability, and heattreated
strength make them ideal for Indian infrastructure projects where long service life is critical.
