General DIY workshop metal & wood workers machinist daily use hand tools (4"/100 mm Metric Feeler Gauge (20 Blade))

• Extended 20-Blade Precision Set: This professional feeler gauge set features 20 distinct blade thicknesses, providing a wider range and finer resolution than standard sets. It is engineered for those who require ultimate precision in mechanical adjustments.
• High-Accuracy Gap Measurement: The 4-inch (100 mm) long blades allow you to reach deep into complex assemblies to accurately measure valve lash, spark plug gaps, bearing clearances, and other critical tolerances.
• Hardened Alloy Steel Construction: Every blade is manufactured from premium-grade hardened and tempered steel. This high-tensile material ensures the blades maintain their calibrated thickness over time and retain their flat shape even after repeated use.
• Permanent Metric Markings: Each blade is clearly laser-etched or stamped with its exact thickness in millimeters (mm). These permanent markings are resistant to oil, grease, and solvents, ensuring high visibility and error-free readings in workshop conditions.
• Smooth 360° Swivel & Lock: All 20 blades are housed in a protective metallic case that allows for full 360-degree rotation. The integrated knurled locking nut allows you to select a specific blade and lock it securely in position for easier handling.
• Professional Grade Finish: Produced by Assort Machine Tools Co., this gauge features a sophisticated metallic and black finish. The polished surfaces reduce friction, providing a better "tactile feel" when checking for precise fitment and resistance.
• Lightweight & Compact: Weighing approximately 100 grams with a slim, streamlined profile, this tool fits effortlessly into your pocket or tool apron. It is the ideal instrument for on-the-spot engineering inspections and maintenance.
• Versatile Engineering Utility: From automotive technicians to industrial machinists, this tool is an essential asset for verifying piston ring gaps, tappet clearances, fretwork, and general machine alignment tasks.
