Hardware & Adhesives — Complete Guide
Hardware & adhesives are the small but essential components that hold a building together — the hinges, locks & handles that make doors work; the fasteners that fix everything in place; and the adhesives, grouts & sealants that bond, fill & waterproof joints. Though individually small, the right hardware & adhesives ensure durability, security, hygiene & a professional finish. This category covers all door hardware, fasteners, tile adhesives, sealants & glues.
These materials follow IS 12817 (hinges), IS 2209 (locks), IS 15477 (tile adhesive), ASTM C920 (sealants). Top brands: Godrej, Dorset, Hettich, Hilti, Fischer, Roff, Pidilite (Fevicol), Dow.
Materials in this Category
Three Groups
1. Door / Window Hardware
2. Fasteners
3. Adhesives, Grouts & Sealants
Choosing the Right Bonding Material
Match the material to the job: Tile adhesive for tiles, epoxy grout for wet-area joints, silicone for glass / sanitary / weather joints (not paintable), PU / PVA for wood & mixed bonding, and the right anchor bolt for heavy fixing to concrete. Using the wrong product is the most common cause of failures.
Hardware Material Quick Guide
| Material | Best For |
|---|
| Stainless Steel (SS 304) | Hinges, bolts, fasteners (rust-free) |
| Brass | Premium handles, locks, bolts |
| Zinc Alloy | Economical fittings |
| High-Tensile Steel (8.8+) | Structural bolts |
Cost Overview (Approximate, 2025-26)
| Item | Cost |
|---|
| SS Hinge (per pair) | Rs 60 – 500 |
| Mortise Lock Set | Rs 500 – 4,000 |
| Tower Bolt (SS) | Rs 60 – 450 |
| Anchor Bolts (each) | Rs 10 – 300 |
| Tile Adhesive (per 20 kg) | Rs 250 – 1,100 |
| Epoxy Grout (per kg) | Rs 350 – 900 |
| Silicone Sealant (cartridge) | Rs 120 – 900 |
| PU / PVA Adhesive | Rs 120 – 600 |
Best Practices
- Use SS 304 / brass hardware (rust-free, especially coastal)
- Use 3–4 hinges per door (ball-bearing for heavy)
- Match anchor bolt to load & substrate
- Use tile adhesive (not cement-sand) for vitrified / large tiles
- Use epoxy grout in bathrooms / kitchens (waterproof)
- Use neutral-cure silicone on metal / stone (acetoxy only on glass)
- Use PU for waterproof / mixed-material bonds; PVA for interior wood
- Buy genuine branded products (avoid counterfeits)
- Clean surfaces before bonding / sealing
- Use the correct product for each job

Conclusion
Hardware & adhesives are small components with a big impact on durability, security & finish. Use quality SS / brass door hardware, the right fastener for each load & substrate, tile adhesive & epoxy grout for tiling, silicone for glass / weather joints, and PU / PVA for bonding. The golden rule: match the product to the job — using the wrong adhesive or under-sized fastener is the most common cause of failures. Explore each in detail: hinges, locks & handles, latches & tower bolts, nails, screws & anchor bolts, tile adhesive & epoxy grout, silicone sealants and PU & PVA adhesives.
