• 【STURDY AND DURABLE】: The high-class steel and heat treatment, quenching, grinding, and hardening processes make this product wear-resistant, corrosion-resistant, impact-resistant, and not easy to be damaged and worn out, which ensures long-term use.
• 【PRACTICAL TOOLS】: These blocks are commonly used in machining, assembly, and quality control, and are one of the key tools to ensure production quality and efficiency
• 【SCIENTIFIC LAYOUT】: Each block has a total of 23 holes, evenly distributed on all sides, and the cross-drilling design can effectively use lower weight and maximum strength.
• 【HIGH ACCURACY】: The 23 holes(five 3/8-16 threaded holes for clamping and 18 untapped holes) are uniform in depth with 0.0002'' accuracy, which can ensure precision and consistency in industrial applications.
• 【5 PAIRS】: Each group contains two paired blocks. 5 pairs are supplied in accurate pairs that can meet batch requirements, reducing manual calibration costs and ensuring stability and consistency.
