Reference
The reference data we get asked for most often, published rather than emailed. Written for engineers and buyers specifying components, not as marketing copy. If something you need is missing, ask and we will add it.
Fasteners
Coarse and fine pitch, tensile stress area by size, and what 8.8, 10.9, 12.9, A2-70 and A4-80 actually mean in MPa.
Indicative torque by size and property class, why the friction coefficient dominates the answer, and how to read a torque table without being misled by it.
303, 304 and 316 compared, the A2 and A4 designations, why free-machining 303 is not a marine grade, and galling.
Electroplated zinc, zinc flake, zinc-nickel and passivation compared on corrosion performance, cost and hydrogen embrittlement risk.
Point sizes, drill capacity, and how to choose between self-drilling, self-tapping and thread-forming for a given material.
Connectors
PBT, PA66, the high-temperature polyamides, LCP, PP and TPE compared on temperature, moisture absorption, flow and cost.
Gold, tin and silver contact finishes, mating cycles, fretting corrosion, and why a connector's current rating is a temperature-rise number.
Quality & programs
What the certificate actually covers, the five PPAP submission levels, the eighteen elements, and what to agree before tooling is cut.
ARO, tooling, first articles, transit and the buffer nobody quotes. How to plan a launch around a Taiwan or China supplier without being surprised.
