Question 2

Why choose Primus India as your fastener manufacturer in India?

Accepted Answer

Primus India is trusted by procurement managers, structural contractors, and PEB fabricators because our fasteners are engineered for real-world Indian conditions — heat, humidity, coastal salt exposure, and heavy monsoon loads — not just catalogue specifications also have Certifications. We combine an ISO 9001 compliant manufacturing process with rigorous testing, including Kesternich cycles and 1000-hour salt spray testing, and back every product with our PriSeal Ruspert Polymer Coating and Trishul drill point technology for faster, safer installation. As a fastener manufacturer in India rather than a reseller, we control quality from raw material through to the finished, head-marked screw, and we offer full product traceability on request. Combined with responsive technical support and the ability to handle both Bulk Industrial Orders And Custom-Engineered Fasteners, Primus India is built to be a long-term fastening partner, not a one-time supplier.

Question 3

Which industries use Primus fasteners?

Accepted Answer

Primus fasteners are used across metal roofing and cladding, pre-engineered building (PEB) construction, warehousing and logistics facilities, solar mounting structures, cold storage and insulated panel buildings, and general industrial fabrication. Our self drilling screws and roofing fasteners are common on sites ranging from factory sheds and Tier-1 infrastructure projects to smaller commercial roofing jobs, while our fiber cement board fasteners and polycarbonate sheet fasteners serve architectural cladding and skylight applications. PUF panel fasteners are widely used in cold chain and insulated panel buildings where thermal sealing matters as much as mechanical strength. Because requirements differ significantly between a coastal solar farm and an inland warehouse, we recommend speaking with our technical team about your specific substrate, load, and environmental conditions before finalising a fastener specification.

Question 4

Where is Primus India located and how long has the company been manufacturing fasteners?

Accepted Answer

Primus India, operated by Primus Fasteners India, is based in Pune, Maharashtra — one of India's most active industrial and manufacturing hubs — and has been supplying Self Drilling Screws and construction fasteners to clients across the country for over a decade. Our fasteners are engineered at an ISO 9001-compliant manufacturing facility, with quality control and testing processes designed to meet international standards such as ASTM and AS 3566. From our Pune base, we serve procurement managers, structural contractors, and PEB fabricators across major Indian markets including Mumbai, Ahmedabad, Rajkot, Chennai, Bangalore, Hyderabad, Delhi, Ludhiana, and Coimbatore. Being centrally positioned in Pune allows us to serve both western and pan-India industrial corridors efficiently while maintaining consistent quality control across every batch we ship.

Question 5

What makes Primus India different from other fastener suppliers?

Accepted Answer

Many fastener suppliers sell what's available; Primus India engineers fasteners for the specific conditions a project will face. Our PriSeal Ruspert Polymer Coating and Trishul drill point are designed to solve real, recurring field problems — corrosion in coastal and humid climates, and slow or inconsistent drilling on thicker steel purlins. We test to recognised standards, including ASTM B117 and AS 3566.2 with Kesternich and 1000-hour salt spray testing, and back this with an ISO 9001 compliant manufacturing process and product traceability. Unlike suppliers who simply pass through generic stock, we work directly with structural contractors and project engineers to match the right screw diameter, coating, and washer to the substrate, wind load, and environment. That combination of engineering focus, documented testing, and responsive technical support is what sets Primus India apart among fastener suppliers in India.

Question 6

Do you supply pan-India or only in specific regions?

Accepted Answer

Primus India supplies construction fasteners and industrial fasteners across India from our India Pune manufacturing and Taiwan Kaohsiung Manufacturing dispatch base, serving contractors and fabricators in major markets including Mumbai, Ahmedabad, Rajkot, Chennai, Bangalore, Hyderabad, Delhi, Ludhiana, and Coimbatore, Guwahati, in addition to Pune itself. Whether you're sourcing roofing screws for a metal shed in Rajasthan, PEB fasteners for a warehouse in Gujarat, or stitching screws for a cladding project in Tamil Nadu, our logistics network is built to support pan-India delivery for both retail and bulk industrial orders. For large or time-sensitive projects, we recommend confirming delivery timelines with our sales team in advance, since lead times can vary based on order volume, product customisation, and destination.
