For your buttress connections to be compliant under the 16th edition of the API 5B, you must inspect run-out. When inspecting buttress run-out with a Gagemaker BR-2001, inspectors often question where to place the contact point on the thread. Now, the new API 5B Section 126.96.36.199 specifies the location of the inspection point. When the […]

For your buttress connections to be compliant under the 16th edition of the API 5B, you must inspect either the groove width or the tooth thickness. Gagemaker groove width Go/NoGo gages (GW-1000 Series) are a quick and easy method to check your groove width. If your inspection shows a problem or a failed part, you […]
Often on the shop floor you would like to verify the settings of the gage you are using.There are several simple methods to ensure your settings stay correct. Today’s tip covers the MRP® crest diameter and ovality gage and coupling inspection. When using an MRP® crest diameter gage to inspect crest diameter on a coupling, […]
When using a rod standard or gauge blocks to set the “B” dimension (the distance between the shoe and the wear pad) on an MRP® gage, the position of both the shoe and arm are crucial. To ensure proper position when locking an arm, place and hold your finger on the shoe against the standard […]
For Tubing and Casing, properly setting a TH-3002R thread height gage is easy, yet often done incorrectly. The setting standard (1014) has a square-shaped notch and a v-shaped notch. First, use the square-shaped notch, zero the gage. Then, rotate the standard and use the v-shaped notch to verify the gage is correctly zeroed. If the […]
Tired of measuring Buttress Thread groove widths using old Go/No Go gages or by hauling mold samples to an optical comparator? As an easier alternative, Gagemaker now provides a gage to directly measure tooth width easily wherever the part is. The TW-6001 gage comes equipped with a .0005″ reading indicator and a setting standard to […]
When using an MRP to inspect a coupling’s Pitch Diameter, mark the location of the MRP on the face of the 1st machined part, and record the gage reading. Leave this 1st machined part nearby to verify between each additional machined coupling that the gage is still set properly.
Functional thread rolls are manufactured in matched pairs offset by one-half pitch to allow them to sit in a thread’s helical path (groove). Sometimes inspectors or machinists are unsure if they have properly positioned the rolls in the correct helical path. To avoid such issues, simply use a blue Sharpie® to draw a line in […]
While a certified Gagemaker setting standard is the preferred practice for Straight Threads, in a pinch, you can use gage blocks to set a two-point Gagemaker lead gage without a proper standard. Create a gage block stack-up for the necessary interval then place between the points. Hold the face of the stackup against the fixed […]
