Type in your dogbone end geometry, load, and test temperature. Build A Grip sizes a clevis grip against it, checks every failure mode, and hands you a STEP file and a dimensioned engineering drawing — in about a second.
Most grip problems are geometry problems. You already know your specimen — we start there, and everything else is derived and checked.
Width, thickness, pin hole diameter, and edge distance of your dogbone tab. Add the load, the test temperature, and the threaded interface on your load train.
Ear thickness, lug width, bore, shank, and thread engagement are solved against net-section tension, bearing, shear tear-out, pin double shear, pin bending, and thread stripping — using temperature-corrected allowables.
A watertight STEP AP214 solid you can drop straight into your CAD assembly, plus a two-sheet PDF: dimensioned orthographic drawing and the full stress calculation record.
Every field updates the solid model, the strength checks, and the downloads immediately. Nothing leaves your browser.
Allowables below are the values the configurator actually uses. Room temperature is 293 K, LN2 is 77 K, LHe is 4 K.
Pin-loaded double-shear clevises for flat, sheet, and dogbone specimens. Sized to your tab, not to a catalogue.
Button-head and threaded-end specimen adapters. In the configurator queue — talk to us in the meantime.
4 K and 77 K load trains with differential-contraction clearances built into the fit stack.
M16, M30, and 1.250”-12 interfaces to bridge whatever is already bolted to your frame.
Configure your grip above, then hit the button — it opens an email pre-filled with the full parameter record so we can quote without a back-and-forth.
