Toolmakers' Spring-Type
Calipers and Dividers with round legs and solid nut Starrett Toolmakers' Calipers and Dividers are the finest tools of their type. Designed for toolmakers and all good mechanics who require finer adjustment and better balance so a more sensitive "feel" can be obtained. Precision made to rigid Starrett standards throughout. The fulcrum stud is hardened and the bearing surfaces of the legs are large enough to prevent any side deflection. The bow spring is strong and flexible, and the adjustment is centrally located in the legs to assure smooth action. |

"Fay" Spring-Type
Calipers and Dividers with heavy square legs and quick-spring or
solid nut Starrett "Fay" Calipers and Dividers feature exceptionally rugged construction. The legs are made from heavy square stock, machined to a smooth taper. The fulcrum stud is hardened and has a large bearing surface to prevent side deflection of the legs. The bow spring is both strong and flexible, and the adjustment screw is centrally located in the legs to assure smooth action. Furnished in either spring nut or solid nut models. The Starrett quick-adjusting automatic-closing spring nut is designed for making quick, positive adjustments. The threads of the nut firmly engage the screw at the slightest pressure from the leg. When the pressure is withdrawn, the nut automatically releases itself, sliding freely over the screw. |

"Yankee" Spring-Type
Calipers and Dividers with flat legs and quick-spring or solid
nut Starrett "Yankee" Calipers and Dividers are made from a high-grade steel and well finished. The legs are made of flat stock and are very durable. The fulcrum stud is hardened and has a smooth bearing surface. The bow spring, although flexible, is exceedingly strong to assure reliability. All sizes are available with either spring nut or solid nut. The Starrett quick-adjusting automatic-closing spring nut is designed for making fast, positive adjustments. The threads of the nut firmly engage the screw at the slightest pressure from the leg. When the pressure is withdrawn, the nut automatically releases itself, sliding freely over the screw. This feature saves time in opening and closing. |

"Yankee" Spring-Type
Hermaphrodite Calipers with quick-spring or solid nut These calipers have the same overall design and finish features as our "Yankee" calipers. One leg is bowed for clearance and capacity. The fine-adjustment screw allows for close setting accuracy. This tool will scribe lines parallel to outside edges easily and consistently. |

Thread Calipers Starrett Thread Calipers are designed for measuring screw threads. The points of the No. 179 are tapered for measuring outside threads, and the points of No. 184 are shaped for inside threads. These calipers are made from a high-grade steel and well finished. The fulcrum stud is hardened and has a smooth bearing surface. The bow spring, although flexible, is exceedingly strong to assure reliability. Furnished with solid nut only. |

Firm-Joint
Hermaphrodite Calipers Starrett Hermaphrodite Calipers are used in layout work for locating and testing centers, laying off distances from an edge, etc. We offer a complete choice from which machinists and toolmakers can select to best suit their requirements. The rugged, properly shaped legs are made of finely finished, high-grade steel. Sizes listed are the lengths of the legs. Actual measuring capacity is approximately one-third greater than the leg size. No. 243 6" (150 mm) This caliper features a round, adjustable leg and an improved firm-joint, which allows the joint to be adjusted at any tension. The leg that holds the adjustable point is offset. |
 |
Hermaphrodite Calipers No. 563 This caliper has a round, adjustable point held by a straight leg. An improved, firm-joint feature permits the joint to be adjusted at any desired tension. No. 42 Series These calipers have an adjustable point, locking joint and fine-adjustment feature for close measurements. After the legs have been set to approximate size and the joint locked, the final adjustment is made by a few turns of the knurled adjusting nut. |
 |
Improved Firm-Joint
Calipers Starrett Firm-Joint Calipers have an improved joint, designed so the tension can be adjusted as desired. After adjustment has been made, the tension will not change with the opening and closing of the legs. The legs are made from a high-grade steel, are ruggedly constructed and are well-finished. The sizes listed are the lengths of the legs. Their actual measuring capacity is about one-third greater than the given size of the legs; for example, the 36" size will caliper a 46" diameter. |

Lock-Joint Calipers
with fine-adjustment These calipers feature a joint which can be quickly and firmly locked by a partial turn of the large knurled disc. A spring washer under the disc maintains proper tension of the legs when the joint is unlocked. These calipers are also provided with an adjusting screw to permit fine-adjustments for close measurements. After the legs have been set to approximate size and the joint locked, the final adjustment is made by a few turns of the knurled adjusting nut. The legs are made of a high-grade steel and well shaped. They are ruggedly constructed and nicely finished. The sizes listed are leg lengths. Their actual measuring capacity is about one-third greater than the given size of the legs. |

Improved Trammel Heads
with divider points, pencil socket Used to measure the distance between points that are too great to be reached with dividers. The heads are die cast with black wrinkle finish and have hardened, forged steel divider points. The points screw into the heads, and the pencil socket accompanying each set of trammel heads can be used in place of either point. No. 50A has an adjustable point. Longer points (5"/125 mm) are also available. A beam is not furnished with these trammels. The heads will accommodate a beam up to 3/8" (9.5 mm) thick and 3/4" (19 mm) wide. |
