FAQs — Pin Type Anchor Bolt
1. What is a pin type anchor bolt and what is it used for?
It's a fastener that grips concrete from the inside. You drill a hole, push the bolt in, and hit it with a hammer. It expands inside the hole and locks in place — ready to hold a machine base, base plate, panel, or bracket. No glue, no waiting.
2. Which size pin type anchor bolt do I need for my job?
For light work like cable trays and conduit brackets, 6mm or 8mm is enough. For electrical panels and small equipment, use 10mm. For machine bases and structural base plates, go with 12mm or 14mm. For heavy compressors, large pumps, or infrastructure work, use 16mm or 19mm. Not sure? Tell us what you're fixing — we'll confirm the right size.
3. How much weight can a pin type anchor bolt hold?
A 6mm bolt holds up to 350 kg. A 10mm holds up to 1,250 kg. A 12mm holds up to 1,750 kg. A 16mm bolt at full depth holds up to 3,870 kg. Keep in mind — vibrating machines like compressors push sideways on the bolt, not just downward. Always check the sideways strength, not just the pull-out figure.
4. Can I use these anchor bolts on any wall or floor surface?
It works on solid concrete, hard stone, and solid brick. It does not work on hollow blocks, lightweight AAC blocks, or damaged old concrete — the bolt needs solid material around it to grip. If your surface is hollow block or AAC, call us and we'll suggest the right alternative.
5. What material should I choose — normal steel, galvanised, or stainless steel?
For dry indoor locations, normal zinc-coated mild steel is fine. For outdoor or rain-exposed areas, go with hot-dip galvanised. For coastal regions like Mumbai or Ratnagiri, use stainless steel SS304. For chemical plants or pharma facilities, SS316 is the right choice. Getting this wrong is costly — replacing a corroded anchor after installation is far harder than choosing the right material upfront.
6. Are these bolts made to IS standard and do you provide certificates?
Yes. Every bolt is manufactured to IS, DIN, and ASTM standards — the same standards asked for in government and EPC tenders. We are ISO 9001:2015 certified. Material test certificates and compliance documents are available on request. Just mention it when you enquire.
