Specification Brand : BORDSTRACT BulletPoint1 : [MAIN PURPOSE] This less steel taper aperture gauge is specifically designed for accurately measuring the inner diameter of thin-walled objects, such as plastic tubes, pipes, and similar components. It provides a and efficient solution for determining inner hole dimensions where traditional calipers or micrometers prove inadequate. BulletPoint2 : [MEASURING RANGE] Covering a measuring range of 1mm to 6.5mm, this aperture gauge accommodates a variety of hole sizes commonly encountered in DIY projects, industrial applications, and more. The precise 0.1mm graduations ensure accurate readings for critical measurements, making it an indispensable tool for quality control and precision work. BulletPoint3 : [LESS STEEL] Crafted from high-quality less steel, this taper aperture gauge is built to withstand the rigors of frequent use in demanding environments. The rust and rust-resist properties of less steel ensure long-lasting performance and maintain the gauge's accuracy over time, even in humid or harsh conditions. BulletPoint4 : [LASER SCALE] Obtain quick and accurate readings with the laser-engraved numeral scale etched directly onto the cone surface of the gauge. This permanent marking technique ensures high visibility and eliminates the risk of fading or wearing off, providing clear and measurements for years to come. BulletPoint5 : [SIMPLE STRUCTURE] This taper aperture gauge features a straightforward and user-friendly design for quick and effortless measurements. Simply insert the tapered end into the hole until the largest possible diameter is reached, and read the corresponding measurement etched on the gauge's surface.
