## What is Nut & Bolt?

You're in charge of a nut and bolt factory! In Nut & Bolt, you take raw steel through a nine-station galvanizing line, from degreasing all the way to packing, and sell the finished parts. The better you build your line, the faster your factory grows.

A REAL PRODUCTION LINE
Degreasing, Rinse, Acid Bath, Flux, Dryer, Basket Loading, Centrifuge Galvanizing and Packing. Every station has its own speed and capacity. If one station falls behind, the queue in front of it fills up and the line jams. Find the bottleneck, upgrade the right station and keep the line flowing.

UPGRADE AND AUTOMATE
Every station has its own upgrades: heater count, centrifuge RPM, crane speed, extra tanks... Automate your stations, speed up the feed and power up the conveyor.

ORDERS AND SURPRISES
Race the clock to deliver orders and grab bonus rewards. Open the chests that pop up beside the line. When a breakdown hits, decide fast: repair it now, or wait it out?

MATERIALS AND PRESTIGE
Start with black steel and unlock Alloy Steel 8.8 and Stainless A2 as you level up. Once you've earned enough, build a new factory and start stronger with permanent reputation points.

GOALS
60 achievements, daily quests, daily login rewards and a level system. The line runs faster on the night shift.

IT KEEPS RUNNING WHILE YOU'RE AWAY
Even when you close the game, the line keeps producing. Your earnings are waiting when you come back.

A production and management game you can enjoy at a relaxed pace, with plenty to chew on for players who love optimizing a line. Foreman Rıza will show you the ropes. Come on, fire up the line!

Also includes a Galvanizing Guide: learn what really happens at each station of a hot-dip galvanizing plant.

Available in 17 languages.

Note: The game requires an internet connection. It contains optional ads.
