These gauges have 18 leaves that swing out when you want to quickly check an angle. They're more convenient than a protractor when identifying 45° and smaller angles. The 14 _1/2° angle leaf measures half the Acme standard 29° angle.

Angle Gauge Block Sets

Create and check angles with these precision-ground blocks. Each block is labeled with its angle. Use them to assist in machine setup, precision layout, and inspection processes. Combine multiple blocks to create a specific angle. For example, stack the 20° block and the 2° block to make a 22° angle.

Electronic Chamfer Gauges

Whether a chamfered edge is in a screw hole or on the end of a rotary shaft, these gauges find its diameter. Use them to confirm the tolerance of edges after milling, drilling, and reaming. They measure chamfers on the inside or outside diameter of your bore. As you trace the probe of these gauges along an edge, an internal sensor records the distance and angle. The calculated diameter displays on the LCD screen for quick readings. All have SPC data output to transfer information to your computer or data processor—you don’t even need any cables.

Choose a gauge with an angle that is greater than or equal to the chamfer angle you are trying to measure.

Digital Levels

Pick these digital levels for repeat leveling tasks and tired eyes. With a digital display for clear reading and an audio alert that sounds when your surface is perfectly level horizontally or vertically, you can quickly align a workpiece before moving on to the next surface. The false zero setting lets you set any position as a reference point when you need to replicate angles on multiple surfaces. You can also view the angle, pitch, or slope of a surface without a separate tool. Use the horizontal and vertical bubble vials on these levels to recalibrate the sensor if needed and as a backup option if your level runs out of battery.

Magnetic Levels—Stick to metal surfaces for hands-free leveling.

Low-Light Levels for Tight Spaces

Level surfaces inside machinery, behind equipment, or anywhere too cramped for light to reach. The vials on these levels illuminate for clear reading without a flashlight. Also known as torpedo levels, their compact size and tapered ends make them ideal when you're leveling short surfaces or working in tight corners. Rest these levels on flat surfaces or fit the side with the V-shaped indentation around pipes and curved shafts.

Pitch-Measuring Levels with LED Vials—Use the incremental marks on the horizontal vial to find the incline of surfaces while you level. LED lights illuminate one vial at a time, so you can read it clearly without the other lights creating glare.

Magnetic Levels—Stick to metal surfaces for hands-free leveling.

Multi-Axis Levels

Simultaneously check if a surface is level horizontally and vertically, as well as front-to-back. Use one of the three main vials on these levels to determine if your surface is completely flat, upright, or at a 45° angle. Plug in the fourth vial to level two axes at the same time. Use them to level cross-sections of pipe, frames, and other three-dimensional parts.

Rest them on flat surfaces or fit the side with the V-shaped indentation around pipes and curved shafts.

Pitch-Measuring Levels—Level and determine pitch with one tool. The horizontal vial has incremental marks that indicate the incline of surfaces such as drainage pipes, conveyor chutes, and roofs.

Two-Axis Surface-Mount Levels

Mount these levels to workbenches, platforms, and tabletops to keep them horizontally level in two directions. Use them to make sure surfaces stay aligned over time.

Screw-On Levels—Fasten these levels to any drillable surface for the most secure mount that won't shake loose, even on vibrating equipment. Fasteners are not included.

Digital Precision Levels

You won’t need to choose between precision or convenience with these levels. Their highly sensitive sensor accurately determines level, even when placed on vibrating machinery and equipment. Clearly read the high-contrast display in any lighting conditions – no need to squint to read vials. They stabilize in five seconds after you position them, so you can quickly check the alignment of one part and move on to the next item. You can also view the angle and slope of a surface without a separate tool. When you need to use these levels under machines or in tight spaces between parts, connect them to your smart device via Bluetooth. The free app lets multiple users view readings remotely.

In addition, the V-shaped indentation on the base means you can rest them on flat and curved surfaces alike. These levels also have a false zero setting lets you set any position as a reference point when you need to replicate angles on multiple surfaces.

Granite Base—Granite chips off instead of denting or deforming when dropped. It also won’t corrode in wet environments like cast iron or steel, so the base always stays accurate.

Levels

Your go-to option for day-to-day leveling. Made from aluminum, these levels won't crack or warp the way plastic ones do. Lay them against everything from building frames to floor tiles to make sure your surface is level horizontally, vertically, or at an angle.

Angle-Measuring Levels—Measure precise angles while leveling without switching tools. To find the angle of your surface, rotate the angle indicator vial until the bubble is level.

Levels for Tight Spaces

Levels

Squeeze these levels into places a standard level would never fit. Their short length and tapered ends make them ideal when you're leveling small parts or working in tight corners. Also known as torpedo levels, they're commonly used by plumbers leveling drains under sinks or by electricians installing components behind electrical panels. Rest them on flat surfaces or fit the side with the V-shaped indentation around pipes and curved shafts.

Heavy Duty Levels

These sturdy levels last longer than typical levels, even if you use them frequently. With four solid sides that form a box shape, they stay flat on surfaces without wobbling and won’t twist or deform over time. The aluminum housing and durable plastic vial won't crack if you step on them or drop them off a ladder or tool tray.

Chamfer Gauges

With Three-Blade

Probe

Check the top diameter of chamfered holes to make sure they’re within tolerance. These gauges are often used for quality control in milling, drilling, and reaming. Press the three-blade probe into a chamfered hole and twist slightly to center. Once the blades touch the hole’s slopes, the dial will display the diameter. Zero-set these gauges on a flat, ground surface when needed.

Choose a gauge with a measuring angle that’s greater than or equal to the angle of the chamfered hole you’re measuring.

Starrett Countersink Gauges

With Cone Probe

Mate your fastener and countersink perfectly for a secure hold with these Starrett gauges. They are often used in vehicle and metal manufacturing to check the top diameter and countersink angle of a hole. When the conical probe touches the hole’s angled walls, the diameter will display on the dial. You can verify the countersink angle based on how snug the probe fits into the hole. Even when you lift the gauge out of the hole, your measurement will stay on the dial until you press the reset button.

Choose a gauge with an angle that’s equal to the angle of the countersunk hole you’re trying to measure.

Countersink Gauges

With Cone Probe

For a flush fit every time, these gauges ensure your fastener and countersink mate perfectly for a secure hold. These gauges are often used to verify the top diameter and angle of holes in precision assemblies. They’re preferred over chamfer gauges, which also measure diameter but don’t check countersink angle. When the conical probe touches the hole’s angled walls, the diameter will display on the dial.

To verify the countersink angle, feel how snug the probe fits into the hole. You’ll also know the angle is incorrect when the reading for the top diameter is a different value than expected. Choose a gauge with an angle that matches that of your hole.
