Meets the performance requirements of Federal Specifications FF-T-79lb, Type 1, Form 1 - Class 5, and ASTM F-1145, except for those provisions required of the contractor.
Turnbuckle assembly combinations include:
Eye and Eye, Hook and Hook, Hook and Eye, Jaw and Jaw & Jaw and Eye.
End fittings are Quenched and Tempered, bodies heat treated by normalizing.
Crosby's Quenched and Tempered end fittings are normalized bodies have enhanced impact properties for greater toughness at all temperatures.
Modified UNJ thread on end fittings for improved fatigue properties.
Turnbuckle eyes are forged elongated, by design, to maximize easy attachment in
Forged jaw ends are fitted with bolts and nuts on sizes 1/4" - 5/8", and pins and cotter on sizes 3/4" - 2-3/4".
TURNBUCKLES RECOMMENDED FOR STRAIGHT OR IN-LINE PULLONLY.
Lock Nuts available for all sizes. Typical hardness levels, Tensile Strengths and Ductility Properties are available for all sizes. Turnbuckles can be furnished proof tested or
Crosby products meet or exceed all the requirements of ASME B30.26including identification, ductility, design factor, proof load and temperature requirements.
Importantly, Crosby products meet other critical performance requirements including fatigue life, impact properties and material traceability, not addressed by ASME B30.26.
