Lightweight Labware
Backers Screw Set
Couldn't load pickup availability
Replacement screw set for Lightweight Labware extrusion backers. Covers the flat-head M3 screws used to fasten Voron backers to 2020 extrusion; choose black oxide, stainless steel, or titanium.
Why these screws
- Sized for Lightweight Labware Titanium Extrusion Backers and the Voron extrusion-backer install pattern.
- Flat-head profile sits cleanly in countersunk backer plates instead of standing proud of the extrusion.
- Use with M3 post-assembly/hammerhead T-nuts in 20-series extrusion; pair with Hammerhead T-Nuts for 20 Series Aluminium Extrusion when you need nuts too.
Specifications
- Black oxide / stainless steel set: 10 × M3x6mm flat-head screws and 20 × M3x8mm flat-head screws.
- Titanium set: 30 × custom Ti M3x7mm flat-head Torx screws.
- Thread: M3 metric, intended for M3 T-nuts in 2020/20-series printer extrusion.
Fitment
- For Voron V2.4 and Trident extrusion-backer installs using Lightweight Labware backers.
- Backers mount opposite the linear rail: top of Y extrusions and rear/top of X depending on rail layout.
Not included
- Backer plates, T-nuts, Torx key, rails, extrusion, or printed parts.
- Check your backer material and countersink before forcing screws; M3 flat heads are easy to strip if misaligned.
“Backer screws for your Ti or SS backers… make the install dead simple.”

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
