CROSBY 1031877 Jaw and Eye Turnbuckle Steel 500 lb Working Load Limit

End fittings are quenched and tempered or normalized, bodies heat treated by normalizing. Hot dip galvanized steel. Hooks are forged with a greater cross sectional area that results in a stronger hook with better fatigue properties. Meets or exceeds all requirements of ASME B30.26 including identification, ductility, design factor, proof load and temperature requirements. Importantly, these turnbuckles meet other critical performance requirements including fatigue life, impact properties and material traceability, not addressed by ASME B30.26. Modified UNJ thread on end fittings for improved fatigue properties. Body has UNC threads.
