Difficulty: MediumMeasuring and Layout Tools

Match each measuring or layout tool on the left with its primary shop application on the right.

  • Thread pitch gaugeIdentifying the profile and number of threads per inch on an unknown fastener
  • Trammel pointsScribing large arcs and circles onto sheet material beyond the span of standard dividers
  • Depth micrometerMeasuring the precise distance from a flat reference surface to the bottom of a recess or blind hole
  • Scratch awlEtching fine, permanent layout guidelines directly onto metal or wood surfaces

Answer

Thread pitch gauge pairs with identifying fastener thread counts; Trammel points pair with scribing large arcs and circles; Depth micrometer pairs with measuring the depth of blind holes or recesses; Scratch awl pairs with etching fine layout lines onto surfaces.
Each tool is matched to its direct shop function: thread pitch gauges check fastener thread spacing, trammel points layout large radiuses on a beam, depth micrometers quantify hole and slot depths with precision, and scratch awls produce crisp scribed layout marks.

Step-by-Step Solution

1
Identify the primary function of the thread pitch gauge
Matches with determining fastener thread pitch and teeth per inch
Thread gauges use precisely cut toothed blades to match the threads of fasteners.
2
Identify the primary function of trammel points
Matches with scribing large circles and arcs on sheet stock
Trammel heads mounted on a beam extend radius layout capacity far beyond standard wing dividers.
3
Identify the primary function of the depth micrometer
Matches with measuring depths of blind holes or steps from a surface
The flat reference base rests across the opening while the screw spindle measures depth down into the cavity.
4
Identify the primary function of the scratch awl
Matches with etching fine layout reference lines directly onto stock
The pointed steel point scores sharp lines that will not smudge like graphite or ink.
