Anchor Fastener FAQs

Yes. Fasteners King is India’s No.1 Fischer channel partner (5 years in a row) and an Authorised Hilti Channel Partner. We supply only original products with a GST invoice in India and a VAT invoice in the UAE. Fake or tampered anchors look almost the same but can fail under load – buying from an authorised channel is the only way to be sure.

Delhi (Chawri Bazar) and Guwahati (AT Road) in India, and Dubai (Al Quoz Industrial 4) in the UAE. Delhi serves North India, Guwahati serves the North East, and Dubai serves all seven emirates.

We dispatch within 24 hours of your purchase order, subject to stock availability. Our on-time dispatch rate is 98.4%. A late anchor delivery can hold up a whole crew – tell us your site deadline when you order.

Freight is paid by the customer. Share your site location on WhatsApp and we will tell you the transport options.

Many Indian product pages show an indicative price (GST extra). Prices change often, so WhatsApp us for today’s best price. Bulk and project rates are available.

Send your BOQ, drawing or product list on WhatsApp with your site location. Our team usually replies with price and stock within minutes during office hours (11 AM – 7 PM).

Fasteners can be exchanged within 3 days of the invoice date if unused, in original packaging and with the invoice. Chemical mortars and cartridges are never exchanged or returned, because they have an expiry date and their storage cannot be verified once sold. There are no refunds. Read the full exchange policy.

Yes. Our Dubai branch exports worldwide. Our Indian branches export to Nepal and Bangladesh.

A chemical anchor is an injection mortar (resin) pumped into a drilled hole. A threaded rod or rebar is set in the mortar, which hardens and bonds the steel to the concrete. It holds heavier loads than most mechanical anchors and puts no expansion stress on the concrete.

Use a chemical anchor for heavy loads, rebar, fixings close to edges, and where the concrete must not be stressed. Use a mechanical anchor (wedge, sleeve or drop-in) when you need to load the fixing immediately and the load is moderate. Choosing the wrong type is a common reason for failed pull-out tests.

It depends on the mortar and the temperature – from under an hour for fast vinylester mortars to many hours for epoxies. Always check the curing table printed on the cartridge. Loading an anchor before it has cured is one of the most common causes of failure.

Epoxy (like FIS EM Plus or HIT-RE 500 V4) is for rebar, heavy structural loads and deep or wet holes, but cures slowly. Vinylester (like FIS V Plus) cures fast, so the fixing can take load the same day. See our FIS EM Plus vs FIS V Plus guide.

It depends on the hole diameter, depth and number of holes. Use our free chemical volume calculator – Delhi, Guwahati or Dubai – or send your details on WhatsApp.

The hole is usually slightly bigger than the rod – for example, about 14 mm for an M12 rod with many mortars. Always follow the setting table for the exact product, because the wrong hole size reduces the load the anchor can carry.

Blow, brush, blow – blow out the dust, brush the hole with the right-size brush, and blow again. Dust left in the hole is the biggest single cause of weak chemical anchors.

Only with a mortar approved for it. FIS EM Plus, for example, can be used in water-filled holes. Using the wrong mortar in a wet hole can cut its strength sharply.

Yes, with the right mortar and a perforated sleeve for hollow material. Tell us the wall type and we will suggest the right system.

Store them in a cool, dry place out of direct sun and use them before the expiry date. Heat shortens shelf life – which matters especially on UAE sites.

Wedge (bolt) anchors suit steel structures and heavy fixings in solid concrete. Sleeve anchors suit medium loads and a wider range of base materials. Drop-in (bullet) anchors sit flush and suit overhead fixings with threaded rods – pipes, ducts and cable trays.

Most concrete in a building cracks slightly under load. Anchors approved for cracked concrete (such as Hilti HST4 or Fischer FAZ II Plus) keep their hold when a crack runs through the hole. Using a non-approved anchor in a structural fixing is a real safety risk.

Follow the minimum embedment depth in the product’s setting table. Setting an anchor too shallow is a common reason for low pull-out values.

For outdoor, coastal or humid sites, choose stainless steel (A4 / R grade) or a suitable coating. Zinc-plated anchors can rust outdoors and lose strength over time.

Yes – FastenKing, our own range of chemical anchors, wedge and bullet anchors and dispenser guns. See the FastenKing range.

A pull-out test checks on site that an installed anchor holds the required load. Many consultants ask for it before handover. Read our pull-out test guide.

Yes, in India we can arrange on-site anchor pull-out testing. Ask our Delhi or Guwahati team on WhatsApp.

Check the packaging, printing, batch details and the seller. The safest step is to buy from an authorised channel. See how to identify original Fischer anchors and chemicals.

Yes – Fasteners King LLC delivers to all seven emirates from our Al Quoz, Dubai warehouse, and exports worldwide.

Hilti, Fischer, Würth and our own FastenKing range, along with Milwaukee tools.

Yes. In hot weather the working (gel) time is much shorter, so mix and inject one hole at a time and check the cartridge’s temperature table. Store cartridges in the shade.
