Lock Bolts
The fasteners in this section belong to a family known as lock bolts. Lock bolts are two piece fasteners which offer very high strength, high security joints in applications that require the most robust fastening solution. Another commonly used term for lock bolts is Huck bolts.
Lock bolts are not blind fasteners and require access from both sides to allow fitting.
To install a lock bolt the pin part of the fastener is inserted into a pre-prepared hole in the application. From the other side a collar is pushed onto the tail of the pin. A power tool is then applied to the pin tail. When the tool is operated, the collar is drawn up the pin until a pre-determined clamp load is applied to the joint. The collar is then swaged onto the pin and secured. The portion of the pin held in the tool is then broken off and ejected.

NeoBolt® is a newly designed, high-strength non-breakstem structural two-piece fastener. It provides a similar function to a conventional lockbolt however the pin doesn't break when the fastener is installed.
The Avdel Avbolt® heavy duty fastener is a new development in structural blind fastener design with high strength, and tamper resistance. Avbolt is Intended for use in heavy-duty applications such as construction, container, railway, mining and HGV.
Avdelok is a two piece lock bolt fastener, offering the very best shear and tension performance. Designed for use in very high load applications, Avdelok is commonly used in commercial vehicle, bus and rail construction, as well as heavy duty enclosure construction.
Maxlok is a two piece lock bolt fastener. Unlike most lock bolts, Maxlok has an extended grip range that allows just one length of pin to be used in a great many material thicknesses.
Avtainer is a high strength steel fastener and shell, designed for joining composite panels to metal. Installed like an ordinary lock bolt, Avtainer has a large diameter low profile head.
Installed Avdelok XT fasteners provide a minimum shear, tensile and pre-load strength, which is equivalent to or exceeds property class 8.8 or ASTM A-325 standards. Made to British Standard B7805: Part 2:1997, the Avdelok XT fastener is the perfect alternative to grade 8.8 threaded fasteners, providing a permanent, high tensile friction grip joint but without the risk of loosening.
