Specialist fastener manufacturer Seac has extended its novel range of Polytop polymer-headed rivets with a new series of Multigrip rivets with moulded self-masking self-coloured heads.
Specialist fastener manufacturer Seac has extended its novel range of Polytop polymer-headed rivets with a new series of Multigrip rivets with moulded self-masking self-coloured heads.
Multigrip rivets can clamp materials over a wider range of thicknesses than standard blind rivets.
These fasteners expand radially, which ensures a tight joint even with oversize or irregular holes.
Usually, Multigrip rivets will replace the need to stock three different size rivets.
Polytop fasteners blend unobtrusively with base materials, so they can be used in visible positions where ordinary fasteners would be unacceptable without extra finishing.
They are a cost-effective alternative to painted or capped rivets and can usually offer significant cost savings over hidden fastening systems.
Because they fix and finish in a single step, they can cut production time and labour costs.
The fastener is based on a Multigrip 3/16th (4.8mm) diameter aluminium rivet.
A wide range of colours can be specified and lengths from 10.5 to 24.5mm.
Standard manual or automated rivet setting tools can be used and the raw material grip range is from 1.5 to 20.0mm.
These rivets are not simply plastic-coated.
The heads are encapsulated by a high-precision polymer profile injection moulded onto them.
The material used is Acetal which is resistant to most chemicals including petrol and alkalis.
In some applications, the Polytop Multigrip will provide a better seal against dust, gasses, and liquids than a standard rivet.
