• Its new range of Huckbolt fasteners, the metric MHP series, combines superior tensile strength with faster, more precise installation, claims Huck-United Kingdom.
Only visual inspection is required, dispensing with the need for subsequent, time consuming, torque wrench checking of integrity, it says.
E W Pomfret, engineering director of Contractors' Plant (North West), part of the Pochin Group, says a major advantage of using Huckbolts is ". . . the reduction in total service time spent on checking excellent reliability. • ." The fastener is interchangeable with threaded systems, offering Grade 8 (A490) strength of mechanical fastening. By contrast with conventional threaded bolts, however, its streamlined groove contour reduces the concentration of stress, combining with the larger groove cross-section to prolong fatigue resistance — an advantage in applications where the fastener is subjected to continual, intense vibration.
Vibration resistance is additionally enhanced by the full contact achieved by the locking collar swaged into discreet annular locking grooves. Applications demanding temperproof joints are particularly well served as the locking collar is totally resistant to attack by standard tools, says Huck-UK.
