One group, five units
Nothing leaves the family
Most fastener suppliers forge in one place and send the parts out for plating and coating. We do not. Forging, fastener manufacturing, electroplating, zinc flake and pre-applied thread treatment all sit within a few kilometres of each other on Hissar Road, under the same management and the same quality system.
ElectroplatingEst. 2012
Riya Enterprises
Barrel electroplating for automotive and non automotive parts. Zinc and zinc alloy systems, copper nickel, nickel chrome and tin, plus phosphating and polishing.
- Acid and alkaline zinc
- Zinc nickel and zinc iron
- Salt spray tested in house
Pre-applied thread treatmentsEst. 2022
PR Preapplied Services
Authorised partner in India for Tecnologic 3 of Italy. Thread lockers, sealants, anti-seize and nylon patch on automated lines.
- Around 1 crore pieces a month
- ISO 9001:2015 certified
- Torque and sealing tested
Zinc aluminium flake coatingEst. 2023
Riya Zinc Flake Coatings
Authorised applicator for Zincotec. GEOPERT silver and BLACKPERT black systems, dip spin applied, alongside a solvent based automatic line. Open for third party job work across Haryana.
- 1,500 hours plus salt spray
- 150 tonnes a month
- Dip spin and automatic lines
Fastener manufacturingEst. 2024
PR Fasteners
The newest unit in the group, opened in 2024 on Plot 208. It runs a nut forming line on the same range as the original forging shop, so a schedule can be split across both.
- Nut forming line
- Plot 208, HSIIDC
- Same group quality system
The route through the group
Five steps, all of them ours
Cold forging
Certified wire rod goes into multi station nut formers and part formers. Grain flow follows the shape instead of being cut through it, which is why a cold forged nut outlasts a machined one.
Nut formers, part formers, in-house tool room and EDM
Turning and secondary
CNC turning centres, VMC and tapping lines take the forged blank to the close tolerances on your print. Shot blasting, friction press and fibre laser marking sit on the same floor.

Coating
Riya Zinc Flake applies zinc aluminium flake by dip spin, water based GEOPERT and BLACKPERT as standard with a solvent based line alongside it. Past 1,500 hours of salt spray at six to eight microns, and no hydrogen embrittlement risk on high tensile parts.

Pre-applied
PR Preapplied Services puts Tecnologic 3 thread lockers, sealants and anti-seize onto the thread on automated lines, so the fastener arrives at your station ready to run.
Screw and disc coaters, induction heater, box oven
Proving it
Nothing ships on assumption. Hardness, roughness, profile projector, air gauge, XRF, coating thickness, salt spray to ASTM B117 and torque testing, all in our own lab.

Nuts, specials and turned parts
A sample of what runs regularly. The full range is wider, and specials to print are routine work here, so send the drawing and we will quote it.
Boring, in the best way
Fastener buying goes wrong in predictable places: a late batch, a coating that fails salt spray, a torque figure nobody can reproduce. We have spent sixteen years removing those three problems from the list.
Forged, coated, treated and tested without the part ever leaving the group.
Value pricing
Priced on what the part actually takes to make, not on what the market will bear.
Quality assurance
IATF 16949 systems with a full lab on site, so the report comes from us, not a third party.
Timely shipping
On time dispatch, batch after batch. Ask the customers who have been here ten years.
Dedicated support
You talk to the engineers who run the machines, not to a call desk.
