Connecting rod bolt market seen reaching $1.35B by 2030

The connecting rod bolt market was valued at $0.99 billion in 2025 and is projected to reach $1.35 billion by 2030, driven by automotive production, industrial activity and demand for more durable engine fasteners. North America led the market in 2025, while hybrid powertrains, engine downsizing and aftermarket repair are expected to shape the next phase of growth.

Why it matters: - Connecting rod bolts are a critical engine fastener, and demand rises when vehicle production, engine output and industrial manufacturing expand. - The market’s growth signals stronger demand for high-performance fastening parts used in internal combustion engines, hybrid powertrains and engine refurbishment.

What happened: - The connecting rod bolt market reached $0.99 billion in 2025 and is projected to rise to $1.05 billion in 2026. - The market is forecast to expand to $1.35 billion by 2030, implying a 6.5% compound annual growth rate from 2026 to 2030. - North America was the largest regional market in 2025. - The report also covers Asia-Pacific, South East Asia, Western Europe, Eastern Europe, South America, the Middle East and Africa. - The Business Research Company published the report, “Connecting Rod Bolt Market Report 2026 – Market Size, Trends, And Global Forecast 2026-2035.”

The details: - The market’s recent growth has been driven by global internal combustion engine production, automotive durability requirements, wider use of alloy steel fasteners, expanded OEM automotive capacity and continued reliance on forged fastening systems. - Future growth is expected to come from hybrid powertrains, advanced heat-treated fastening materials, engine downsizing and optimization, and aftermarket repair and engine refurbishment. - Forecast trends include more high-tensile, fatigue-resistant bolts for high-revving engines. - Precision-forged connecting rod bolts are expected to gain preference as automakers push for higher engine reliability. - Lightweight, high-strength alloy fasteners are expected to see more use in performance and racing engines. - Torque stability and consistent bolt preload under extreme conditions remain a key product focus. - A connecting rod bolt links the connecting rod cap to the rod body inside an internal combustion engine. - The bolt is designed to withstand high tensile forces and repeated stress cycles during engine operation. - Its primary job is to maintain clamping force so the crankshaft journal and connecting rod stay connected at high speeds. - That fastening function helps prevent loosening and supports engine reliability, smooth operation and long-term durability. - Automotive production is a major driver because rising urbanization increases demand for personal and commercial vehicles. - In January 2024, the Society of Motor Manufacturers and Traders reported that UK vehicle production reached about 1,025,474 units in 2023, up 17% from the prior year. - Industrialization is also supporting demand as manufacturing and machinery output expands across transportation, construction and factory operations. - Eurostat reported in July 2025 that industrial production in May 2025 rose 3.7% in the euro area and 3.4% in the EU from a year earlier. - The report includes market attractiveness scoring, TAM analysis, company scoring matrices, Excel-based forecasting dashboards, market hotspot infographics, key technology analysis and updated graphics and tables.

Between the lines: - The forecast points to a market that is still anchored in combustion-engine hardware even as the auto industry shifts toward hybrid systems. - The emphasis on heat-treated, fatigue-resistant and precision-forged bolts suggests buyers are paying more for reliability, not just basic fastening capacity. - North America’s lead suggests established automotive and industrial manufacturing bases continue to shape demand.

What's next: - The market is expected to benefit from more hybrid powertrain adoption and continued demand from aftermarket repair channels. - Product development is likely to stay centered on stronger materials, better torque stability and lower-weight designs for high-performance engines. - The Business Research Company is offering a free sample and the full report through its website.
