Every fastener we produce is backed by internationally recognised certifications and rigorous adherence to global manufacturing standards.
Our certifications are not just documents — they represent the processes, discipline, and systems that govern every step of our manufacturing operation.
Quality Management System
ISO 9001:2015 is the world's most recognised quality management standard. It certifies that our entire manufacturing operation — from material procurement to dispatch — follows documented, audited, and continuously improved processes.
Every production step is defined, measured, and controlled
Full material and process traceability for every order
Independent auditors verify our quality systems annually
Formal review cycles drive ongoing process optimisation
Bureau of Indian Standards
All products supplied within India conform to the applicable Bureau of Indian Standards (BIS) specifications. Our in-house testing laboratory verifies compliance before every batch is dispatched, providing complete peace of mind for domestic procurement teams.
Machine Screws — Slotted & Cross-Recess
Self Tapping Screws — Thread-Forming
Technical Supply Conditions for Threaded Fasteners
Hexagon Head Bolts, Screws & Nuts
German & American Standards
For customers integrating our products into international supply chains, our fasteners are manufactured to match DIN (Deutsches Institut für Normung) and ANSI (American National Standards Institute) specifications. This ensures dimensional interchangeability with globally sourced components.
Pan Head Machine Screws — Phillips Drive
Self Tapping Screws — Pan & CSK Head
Self Drilling Screws — Hexagon Flange Head
Slotted & Phillips CSK Head Screws
Good Manufacturing Practices
Good Manufacturing Practices (GMP) certification confirms that our shop floor, equipment, personnel, and procedures meet defined standards of cleanliness, control, and consistency. From housekeeping protocols to operator training records, every aspect of production is governed by documented practice — eliminating variability batch to batch.
Clean, organised workstations with defined material flow paths
Skill matrix and training records maintained for every machine operator
Scheduled maintenance and calibration of all production and inspection equipment
Standard Operating Procedures govern every production and handling task
No batch moves to the next stage without passing the previous checkpoint. This gate-based system eliminates defect propagation before it starts.
Chemical composition & mechanical property verification of all raw wire rod before production commences
Dimensional sampling every 30 minutes during cold heading and thread rolling operations
Hardness and hydrogen embrittlement testing after heat treatment per IS 1367 Part 17
Coating thickness and adhesion tests on plated / galvanised fasteners; salt-spray exposure validation
Final AQL sampling, visual inspection, count verification, and test certificate generation before dispatch
Every shipment from Aggarwal Industries is accompanied by a material test report (MTR) and inspection certificate documenting the specific batch, heat number, dimensional results, and mechanical test values — giving your quality team full traceability.
Our products are designed and manufactured to be fully interchangeable with standard fasteners sourced globally — no custom tooling required on your end.
Standard structural grade — the most widely specified class for industrial applications
High-tensile grade for critical joints in automotive and heavy machinery applications
Corrosion-resistant grades for food, marine, chemical, and outdoor applications
Our team can provide ISO certificates, material test reports, IS compliance declarations, and product-specific dimensional inspection reports — on request for any order.
