Spi 14-687-8 Flexible Steel Rule Metric 3/4 Inch

Product Description

The SPI 14-687-8 is a flexible steel rule with metric graduation, designed for precision measurement in fabrication, machining, and layout work. The rule measures 450 mm in length and 3/4 inches in width, with a thickness of 0.020 inches. The satin chrome-plated finish reduces glare for easier reading in bright shop conditions. The 1/2 mm graduation spacing provides fine metric resolution suitable for close-tolerance work. Machinists, tool-and-die technicians, sheet metal workers, and general fabricators are the primary users of this type of rule.

This flexible rule is suited for applications where a rigid rule cannot conform to a curved or contoured surface. The horizontal scale orientation and slim profile allow it to slip into tight spaces and wrap around cylindrical or irregular workpieces. It is a standard bench and layout tool in machine shops, fabrication facilities, and maintenance environments where metric measurement is required.

Key Features

• Flexible construction allows measurement on curved and contoured surfaces
• Metric graduation with 1/2 mm spacing for fine-resolution readings
• Satin chrome-plated finish minimizes glare and resists corrosion
• 450 mm rule length covers common bench measurement tasks
• 3/4 inch overall width with 0.020 inch thickness for a low-profile fit in tight spaces
• No hook, no magnetic backing — straightforward layout and measurement tool

Compatibility

Designed as a standard flexible steel rule for general metric layout and measurement applications in machine shops, fabrication shops, and maintenance environments.

Installation Notes

No installation is required for this hand tool. Store flat or rolled to prevent permanent set in the blade. Clean the rule surface periodically with a dry cloth to preserve the chrome-plated finish and maintain legibility of the graduation markings. Do not use as a cutting guide with a rotary blade, as this can damage the graduation markings and deform the flexible blade.
