Facom 804.SL Long Feeler Gauge Set

The Facom 804.SL Long Feeler Gauge Set is a metric feeler gauge set designed for precision gap measurement in engine, mechanical, and general engineering applications. The extended 250mm blade length makes it ideally suited for reaching into confined spaces where a standard-length gauge would fall short.

With 19 blades covering a range of thicknesses — from 0.30mm up to 1.00mm in carefully graduated increments — this set provides the coverage needed for a wide variety of clearance checks. Each blade is 10mm wide, offering a good balance between access and contact area when measuring gaps.

The long blade format is particularly useful for valve clearance checking, spark plug gap setting, and bearing clearance measurement, where depth of reach is as important as accuracy. At 210g, the set is substantial enough to feel precise in the hand without being cumbersome.

Features and Benefits:
• 250mm long blades for reaching deep or restricted spaces
• 19 blades providing a comprehensive range of metric thicknesses
• 10mm blade width for stable contact during measurement
• Graduated increments from 0.30mm to 1.00mm for precise gap checking
