I will calculate bolt strength and recommend joint fasteners
About this Gig
Guessing your fastener sizing can lead to expensive disasters. If you buy weak, standard retail hardware-store screws, they can snap or shear off under load. If you over-buy massive structural Grade 8 bolts for a simple framing task, you throw away hundreds of dollars. Even worse, if you mix incompatible metals (like steel bolts in aluminum plates), they will rot and fail from galvanic corrosion.
I analyze your joint's qualitative and quantitative parameters (substrate materials, environmental humidity, vibration risk, and driver tool limits) to run a custom stress and selection check using my advanced Excel sizing engines.
What I determine for your project:
- Fastener Class: Wood screws, concrete anchors, or high-strength bolts.
- Material & Coating: Zinc-plated, hot-dip galvanized, or marine-grade stainless steel (SS316).
- Optimal Drive Style: Torx/Star, Internal Hex, or Hex Flange to prevent head strip-out and tool cam-out.
- Sizing Specs: Gauge/diameter, thread pitch (UNC vs. UNF), embedment depth, and pilot drill bit sizes.
- Engineering Safety Check: Real shear/tensile load limits and stress pass/fail results.

FAQ
Do you recommend imperial (SAE) or metric fasteners?
Both! My calculation and selection engine is fully calibrated to recommend standard US imperial sizes (e.g., #8 wood screws, 3/8" bolts) or metric equivalents (e.g., M5 screws, M10/M12 bolts) depending on your local hardware store's stock.
Can you calculate weld strengths too?
Yes, I can! If your custom brackets are welded to a frame before being bolted, send me a direct message. I can easily create a custom gig add-on to run stress and shear limit checks on fillet or groove welds.
Why do you ask about my screwdriver/tool limitations?
Drive style is where most DIY builds fail. If you use high-torque fasteners with standard Phillips heads, they are highly prone to "cam-out" (stripping). I check your available tools to recommend hex, Torx, or standard drives to ensure your build is easily installable.
What if I have multiple joints in my assembly?
My Basic and Standard packages cover a single structural connection layout. If your build features multiple different connections under different loads, please adjust your quantity at checkout or message me for a custom bundle discount!
