Stainless Steel Crack Gauge Ruler – High Precision Gap Measurement Tool

Meet the ultimate on-site measurement companion: a 304 stainless steel crack gauge ruler engineered for professionals and DIY enthusiasts alike. With a compact 10×4 cm profile and a measurement range of 0.1–1.5 mm (overall ruler up to 80 mm), this slim, pocket-ready tool delivers fast, accurate gap assessments wherever you need them — from concrete walls to door frames and engine clearances.

Key Features

• Fast Gap Assessment: Clearly marked millimeter scale markings make reading gap widths instantaneous, even in demanding on-site environments. Monitor crack expansion on stucco, wood, concrete, and masonry with confidence.
• 2-in-1 Feeler & Hole Gauge: Combines a 0.1–1.5 mm gap measurement scale with an inner diameter comparison function — two tools in one slim card for maximum efficiency during maintenance and inspection tasks.
• Standard Notch Design: Intuitive notch-and-scale layout allows instant visual gap width reference. Use it to verify clearances in automotive valve work, machinery alignment, and hardware installation.
• Portable & Lightweight (~30 g): Ultra-thin sheet profile slips easily into cracks on footings, walls, and joints for immediate width readings. Fits in any toolbox, vest pocket, or site bag.
• Rust-Resistant Stainless Steel Build: 304-grade stainless construction ensures long-lasting durability in outdoor, construction, and industrial environments without corrosion concerns.
• Wide Application Range: Ideal for concrete wall inspection, hardware installation, mechanical assembly, door and window fitting, structural monitoring, civil engineering projects, and woodworking.
