Free Tools for Heavy-Duty Repair Shops
Practical tools built for shop techs and owners. Torque charts, invoice templates, and a website builder — all free, no strings attached.
We built these free tools for diesel mechanics, fleet technicians, and heavy-duty repair shop owners who need practical resources without the hassle. Every torque specification chart, mechanic invoice template, and truck repair shop tool on this page is completely free — no email gate, no signup wall, no credit card. Print them, bookmark them, share them with your crew. They're here because we know what it's like to dig through a 400-page service manual for one torque value.

Are these tools really free with no signup?
Yes. Every tool on this page is completely free. There's no account required, no email gate, and no credit card. The torque charts can be downloaded and printed instantly. The invoice template and website builder require a free ShopView account, but the free plan has no time limit and no payment information is needed.
What torque charts are available for heavy-duty repair?
We currently offer three free torque specification charts: a metric bolt torque chart for Grade 8.8 fasteners (M6 through M36), an SAE/imperial bolt torque chart for Grade 8 fasteners (1/4" through 1-1/2"), and a U-bolt torque chart for cold-formed Grade 5 and Grade 8 U-bolts used in leaf spring and suspension work. All values are based on Caterpillar SENR3130 specifications.
Can I print these torque charts and hang them in my shop?
Absolutely. That's exactly what they're designed for. Each chart downloads as a high-resolution 300 DPI PNG sized at 4" x 7" — perfect for printing as a magnet or sticker to stick on a toolbox, or laminating and hanging on the shop wall. Print as many copies as you need.
Do you have a free invoice template for truck repair shops?
Yes. ShopView offers a free work order and invoicing app that goes far beyond a static template. You can create professional mechanic invoices with itemized parts, labor, shop supplies, and tax — plus track customers, equipment, and job history. It's built specifically for diesel, heavy-duty, and truck repair shops.
Does ShopView offer a free website for my repair shop?
Yes. The ShopView website builder lets you create a professional website for your repair shop in about 15 minutes. Pick a style, add your shop details, upload photos, and go live. Free hosting is included, and no coding or design experience is required. Your site will look like you paid a professional to build it.
