⚡ At a Glance
- • Fastening Reliability: Carbon steel bolts paired with springs maintain a sealed flange connection while allowing controlled movement.
- • Best for: DIY exhaust repairs and routine maintenance on cars, SUVs, trucks and motorcycles.
- • Not ideal for: Exhaust systems that require OEM-specific fasteners or non-standard flange dimensions.
Complete kit includes two screws, two springs and two locking nuts sized at 7.9 x 2.5 cm. Carbon steel construction and springs designed for high temperature resistance deliver durable, vibration-dampening fastening.
Vibration control - with integrated spring
An integrated coil spring sits with the bolt and nut assembly, compressing and extending to absorb engine movement and shocks. Springs are described as having good ductility, which supports performance under repeated thermal cycling.
Maintains a tight flange seal and reduces loosening caused by vibration, helping to prevent exhaust leaks and rattles.
Durability for harsh conditions - with carbon steel construction
Carbon steel fasteners offer higher tensile strength and resistance to breakage compared with weaker alloys. The spring material’s ductility supports thermal tolerance and repeated compression without early failure.
Handles exhaust heat and mechanical stress, reducing the frequency of replacement compared with stripped or corroded fittings.
Quick roadside repairs - with a complete two-screw kit
Kit contains two screws, two springs and two locking nuts, with overall measurements of 7.9 x 2.5 cm and a layout suited to common flange connections. Packaging supplies the basic hardware required for immediate replacement of worn fasteners.
Enables a straightforward swap of stripped or corroded bolts during routine maintenance or emergency repairs.
