Steel Fasteners Is the Most Concentrated Supply Line on the Board, and Taiwan Holds It

Steel Fasteners scores 60 on supply-chain fragility against a 37 average across 57 tracked families, driven by 62 on supplier concentration and 100 on tariff exposure.

Steel Fasteners scores 60 on supply-chain fragility against a 37 average across 57 tracked families, driven by 62 on supplier concentration and 100 on tariff exposure. The composite weights concentration at 35%, import dependence at 30%, tariff exposure at 20% and FX volatility at 15%, so a high score is a statement about how much of the lane runs through one country and one policy regime.

• fragility composite: 60
• board average: 37
• top source: Taiwan

Component scores for this family: concentration 62, import dependence 32, tariff exposure 100 — band: fragile. Taiwan is the top source.

Concentration is a risk you pay for in bad years and not in good ones, which is what makes it easy to carry unexamined. The practical exercise is pricing one credible second source now — invoice, duty, freight — so the switch is a decision rather than a scramble.
