Product Details

The Starrett 98-4 is a 4″ precision machinists’ spirit level, utilised to determine the horizontal plane with a single vial that has a sensitivity of 4 to 4.5 minutes. This level is adjustable to a positive setting, ensuring accuracy for various tasks.

The ground glass vial is specifically designed to resist scratching, delivering clear readings and is securely housed within a brass tube featuring a friction-fit closing to enhance its resistance to breakage. A V-shaped groove along its base facilitates reliable seating when levelling cylindrical items like pipes and conduit.

Constructed with a cast iron base, this level offers durability for extended use in demanding environments. It is commonly used in building trades, engineering, surveying, and metalworking.

Applications of Machinists’ Levels

Levels are essential tools used to establish true horizontal or vertical planes. Traditional spirit levels incorporate a liquid-filled tube (often referred to as a vial) containing a bubble that indicates alignment. When the bubble is centred between designated points on the vial, the surface is determined to be level.

Machinists’ levels are tailored for robust use in workshops, ensuring accuracy under challenging conditions. They can vary in complexity, accommodating needs ranging from basic DIY projects to precision measurements required in larger construction and surveying applications.
