CONSTRUCTION FIXINGS
Fastening for commercial and heavy industry
For demanding assembly applications where welding is not practical or where conventional bolts struggle to provide a guaranteed and retained clamp load quickly and consistently, Avdel® the new range of Infalok® lockbolts.
has developed strength of over 300kN, Infalok® lockbolts can be widely used I
in demanding engineering industries throughout the world including railways, commercial vehicles, construction, mining, bridge, crane building, renewable energy and many structural applications including maintenance/repair. Infalok®
12.7mm to 28.6mm (1 /8 inch) and grip ranges from
6.35mm up to 152.4mm (0.25 inches up to 6 inches). They are available in two different head forms and various finishes. Avdel highlights that Infalok®
nfalok® lockbolts are large diameter, heavy duty, two piece
structural steel fasteners designed to provide exceptionally high strength and secure assembly. Capable of delivering a joint clamp (pre-load) of over 250kN and a tensile
The Avdel 734 AV™ tool range comprises a range of placing
tool options to suit varied working environments. Compact and ergonomic hand tools combined with powerful and robust Enerpac®
pump units offer a new range of high-performance
high-speed installation systems enhanced with built-in features and reliability that, Avdel says, exceed current industry levels. Less service, maintenance and down-time means more cost- effective assembly. The hydraulic pump units are available in voltages from 115/1PH to 480/3PH.
lockbolts offer a wide choice of bolt diameters from /2 inch to 1 1
lockbolts are tamper resistant
and eliminate the risk of vibration loosening during fastened joint service. Also, joint clamp performance offered by Infalok® lockbolts compares to (or exceeds) equivalent sized Metric Property Class 8.8 threaded fasteners. The controlled clamp loads provided by Infalok®
delivers strong, robust joints. In parallel with the Infalok® fasteners, innovative new placing
equipment has been designed by Avdel utilising the very latest technology available resulting in the launch of Avdel’s 734 AV™ installation tool system.
TIMco extends In-Dex screw range
From fixing timber frames to constructing a wooden play area for children, the challenge lies in finding a high quality screw that satisfies user requirements. T. I. Midwood & Co Limited (TIMco) has extended its current range of In-Dex exterior timber screws, which have been designed for multiple wood applications, to provide an efficient solution.
T 78
IMco’s range of hex head In-Dex timber screws has now been extended to include a wafer head 8mm gauge with longer lengths up to 400mm for heavy duty use. Developed for heavier duty fixing needs, TIMco’s new 8mm gauge wafer head In-Dex screws ensure a high pull out resistance and easy insertion to suit customer requirements.
These new additions are available in organic green to offer users a more natural finish to their external constructions as well
as A2 stainless steel. The organic green offers the additional advantage of being tested for 1,000 hours to salt spray resistance, making them suitable for most outdoor applications. The 8mm gauge wafer head In-Dex screws have serrations on the first four threads of the screw to ensure easier insertion. It also features a helix at the top of the thread which relieves torque on insertion and a T30/T40 drive which stops camming out and helps to reduce driver wear. Other features of the In-Dex screws include a 25° sharp point for easier penetration into all wood types, 40° deep single
thread to provide secure fixings and high pull-out resistance and a type 17 slash to reduce torque and the likelihood of the timber splitting when the screw is inserted close to the edge. Simon Midwood, sales and marketing director of TIMco commented: “This new screw was developed with our customers in mind to offer them a wider choice of In-Dex timber screws and provide a solution for their heavier duty fixing needs.”
