Central Tools 35″ x 1/4″ Precision Straight Edge (6431)

The Central Tools 35″ x 1/4″ Precision Straight Edge (6431) is a 35-inch long, 1/4-inch thick tool designed for precision measurement and flatness checking. Made from high-quality, heat-treated steel, it’s an essential tool for engine rebuilding, automotive work, and any application requiring a reliable straight edge. Its compatibility with feeler gauges allows for accurate assessment of warping and unevenness on various surfaces. KEY FEATURES AND BENEFITS: Precision Ground: For accuracy, typically within +/- .0002″ per foot, ensuring reliable measurements. Constructed from Heat-Treated Steel: For stability and resistance to bending. 1/4-Inch Thickness: Provides rigidity and supports accurate measurements. 35-Inch Length: Offers versatility for a range of applications, including small and large engines. SPECIFICATIONS: Length: 35 inches Thickness: 1/4 inch Material: Heat-treated steel Accuracy: Typically +/- .0002″ per foot Coating: Epoxy Model Number: 6431 Brand: Central Tools HOW TO USE: Clean the Surface: Ensure the surface you are checking and the straight edge are clean and free of debris. Position the Straight Edge: Place the straight edge on the surface to be measured, ensuring it makes contact along its length. Use Feeler Gauges: Insert feeler gauges between the straight edge and the surface. Start with a thin gauge and gradually increase the thickness until you find the gauge that just fits snugly. Record Measurements: Note the thickness of the feeler gauge. This indicates the gap between the straight edge and the surface at that point. Check Multiple Points: Repeat steps 3 and 4 at various points along the surface to get a complete picture of the flatness. Interpret Results: Variations in feeler gauge thickness indicate unevenness or warping. BENEFITS OF USING THE CENTRAL TOOLS 35″ X 1/4″ PRECISION STRAIGHT EDGE (6431): Accuracy: The precision grinding ensures reliable measurements, crucial for engine work. Versatility: Suitable for a wide range of applications, from small engines to heavy-duty diesels. Durability: The heat-treated steel construction and epoxy coating provide long-lasting performance. Ease of Use: Simple to use with feeler gauges for quick and accurate flatness checks. Convenient Storage: The hang-up hole allows for easy and safe storage. FEATURES: Epoxy Coating: Protects the steel from corrosion and extends the tool’s lifespan. Hang-Up Hole: For convenient storage. Works Seamlessly with Feeler Gauges: To assess surface flatness. Ideal for Checking Flatness: On engine blocks, cylinder heads, manifolds, and flywheels.
