Screws in Last War: Survival are gear-crafting materials produced mainly through the Material Workshop. According to the supplied information, four Screws can be combined into one Refined Iron Module, which supports more advanced equipment production.
Although Screws may appear to be a minor resource, large-scale gear development can require a steady supply. This guide explains where to obtain Screws, how the conversion works, and when you should save or use them.
What Are Screws Used For?
Screws are intermediate crafting materials connected to the game’s equipment system. Their primary listed use is creating Refined Iron Modules.
- 4 Screws = 1 Refined Iron Module
Refined Iron Modules may then be used in the Gear Factory for higher-tier equipment crafting or related gear progression.
Because several advanced systems may compete for the same materials, check the current Gear Factory recipe before converting a large Screw stockpile.
How to Unlock the Gear Factory
The supplied article states that Headquarters level 9 is required to unlock access to the Gear Factory.
This does not necessarily mean the Gear Factory itself must be level 9 before Screws can be used. Headquarters progression unlocks the building, while separate Gear Factory upgrades may unlock additional recipes and advanced equipment functions.
For more detail, read the Last War Gear Factory guide.
You can also review the Last War Headquarters upgrade guide to plan the building requirements that lead to higher-level equipment systems.
Where to Get Screws
Material Workshop
The Material Workshop is the primary recurring source listed for Screws. It produces materials over time, making regular collection important.
Upgrading the Material Workshop may improve factors such as:
- Production speed
- Storage capacity
- Material quality
- Access to higher-tier production
Confirm the exact benefit of each building level before upgrading, as production details may vary.
Daily and Recurring Activities
Some daily tasks, activity rewards, or supply chests may provide Screws or related gear materials. Review reward previews instead of assuming every daily activity includes them.
Special Events
Limited-time events may offer Screws, Refined Iron Modules, or gear-material chests through milestones, rankings, and exchange stores.
Stores and Markets
Screws or connected materials may occasionally appear in stores or rotating markets. Compare their cost with Upgrade Ore, blueprints, hero resources, and other limited items.
Paid Packs
Some equipment packs may include Screws or pre-crafted Refined Iron Modules. Calculate how many modules the pack actually provides before evaluating its value.
How Screw Conversion Works
The supplied conversion rate is four Screws for one Refined Iron Module.
| Screws | Refined Iron Modules |
|---|---|
| 4 | 1 |
| 20 | 5 |
| 40 | 10 |
| 100 | 25 |
| 400 | 100 |
This table is based on the listed 4-to-1 ratio. Confirm the current recipe in the Material Workshop or Gear Factory before converting exact totals.
Should You Convert Screws Immediately?
Not always. Keeping Screws unconverted may preserve flexibility if future recipes, events, or workshop upgrades change what you need.
Convert Screws when:
- You have selected a specific gear-crafting target.
- You know how many Refined Iron Modules are required.
- The conversion completes an immediate recipe.
- A gear event rewards the related crafting activity.
- You have enough supporting materials for the same upgrade.
Save Screws when:
- You have not chosen which gear to craft.
- Your Gear Factory is not ready.
- You lack other required materials.
- A workshop or equipment event may begin soon.
- You are unsure whether the conversion is reversible.
How to Increase Screw Production
Upgrade the Material Workshop
A stronger Material Workshop may improve production efficiency. Review the upgrade preview to determine whether the improvement justifies the construction cost.
Collect Materials Regularly
If workshop storage reaches its limit, production may stop. Log in and collect materials before the storage capacity fills.
Use Production Bonuses Carefully
Temporary buffs, survivor assignments, research, or event bonuses may improve material production. Apply them when you can collect consistently.
Complete Relevant Events
Events may provide additional Screws or materials that reduce pressure on normal workshop production.
Join an Active Alliance
An active alliance can help through event rewards, building assistance, and access to alliance-related stores. However, direct player-to-player transfers of Screws are not confirmed.
How Screws Fit Into Gear Progression
Screws are only one part of a broader equipment system. Advanced gear may require several different materials at different stages.
These can include:
- Screws
- Refined Iron Modules
- Synthetic Resin
- Dielectric Ceramic
- Upgrade Ore
- Coins
- Legendary Blueprints
- Mythic Blueprints
The Last War gear upgrade charts explain how equipment costs increase from Rare gear to advanced Legendary promotion.
The Last War Dielectric Ceramic guide covers another important material used in higher-level gear development.
Which Gear Should You Craft First?
Do not use Screws simply because enough are available. Choose equipment that supports a permanent hero in your primary formation.
Prioritize gear for:
- Your main damage dealer
- Your strongest front-line defender
- A permanent support hero
- A hero whose current equipment is significantly behind
- An item that completes a useful gear set or milestone
A crafted item provides less value if it is assigned to a temporary hero or cannot be upgraded because other materials are missing.
How to Plan Material Workshop Upgrades
Upgrading the Material Workshop can improve long-term production, but it also consumes construction resources and time.
Consider upgrading when:
- Your Screw production cannot meet Gear Factory demand.
- Storage fills too quickly.
- The next level unlocks a useful material.
- Your construction queue has no higher-priority requirement.
- The upgrade supports a long-term gear objective.
You may delay the upgrade when Headquarters requirements, troop buildings, research structures, or hospitals provide more immediate account value.
Common Screw Mistakes
Ignoring Workshop Storage
Production may stop when storage is full. Collect materials regularly to avoid lost production time.
Converting Every Screw Immediately
Early conversion may reduce flexibility. Produce Refined Iron Modules when you have a specific crafting target.
Crafting Gear for Temporary Heroes
Advanced materials usually provide more value when used for permanent members of your main squad.
Ignoring Other Recipe Requirements
Enough Screws or Refined Iron Modules do not guarantee that a gear item can be completed. Check every required resource.
Confusing Headquarters and Gear Factory Levels
Headquarters level 9 is listed as the building unlock condition. It is not the same as having a level 9 Gear Factory.
Expecting Alliance Members to Transfer Screws
Alliance members may help through event participation and construction assistance, but direct material sharing is not confirmed.
Buying Packs Without Calculating Module Value
Convert the included Screw total into Refined Iron Modules before deciding whether a pack provides enough progress.

Conclusion
Screws are important crafting materials for players developing advanced equipment in Last War: Survival. The Material Workshop provides the main recurring supply, while four Screws can be combined into one Refined Iron Module according to the supplied recipe.
Collect workshop production regularly, avoid converting materials without a clear target, and prioritize equipment for permanent main-squad heroes. Before crafting, verify the complete Gear Factory recipe and all supporting material requirements.
Creating an advanced gear setup requires continuous Material Workshop production, Screws, Refined Iron Modules, Upgrade Ore, Ceramic, blueprints, and developed heroes. Players who prefer to begin with established equipment, stronger heroes, and more advanced account progression can explore a Last War account for sale through Heaven Guardian. Available listings may include different hero rosters, gear development, building levels, Headquarters progression, resources, lifetime warranty, and premium support, depending on the selected account.
