Profil's latest pierce fastening technology

Article Type: New products From: Assembly Automation, Volume 28, Issue 2.

Profil UK's latest high strength mechanical assembly systems including its recently-announced NBR stud, SBF ball pin fastener (Figure 3) and electrical earthing studs demonstrate the cost, quality and productivity benefits of accurately installing high strength, male or female threads in components up to 4.0mm thick. The company's extensive range includes pierce nuts and studs in standard and large flange configurations, as well as shouldered, conical, ultra low profile, high shear, flush fitting and restricted access types. All are available with M6-M12 threads in a variety of materials, for installation in coated or uncoated materials, high tensile, stainless and sandwich steels, aluminium sections and even magnesium castings.

Profil's latest shouldered NBR studs build on the proven abilities of the company's 14mm diameter plain NBR derivatives, which provide precise location of front sub-frame assemblies on the BMW Mini. The new fasteners incorporate a shouldered design for accurate component positioning and a generous thread lead-in for use with high speed nut running equipment.

Suitable for a wide variety of materials, NBR series fasteners enable high strength, watertight fixings to be achieved with an absolute positional accuracy of ±0.2mm. They are ideal for dynamic, static and shock load applications and feature a large flange head for exceptional pull through performance.

Profil's recently announced SBF ball pin fasteners offer a fast and cost- effective method of achieving high strength pivot points in sheet metal components from 0.8 to 2.0mm thick. They incorporate a cold forged 10mm diameter head that is compatible with industry-standard gas springs, making them just as suitable for domestic appliance as vehicle tailgate and bonnet applications.

Other special purpose products include Profil's two-piece electrical earthing fastener; the company's multi- functional RSN “top hat” nut, which produces secure, water-tight mountings for vehicle after-market roof racks along with significant build quality benefits and cost savings of up to $0.50 per car. Similarly, fasteners in Profil's latest corrosion-resistant “Magni” finish, capable of withstanding more than 1,000h of salt spray without rusting, will be showcased at the exhibition demonstrating the system's suitability for even the most aggressive operating environments.

Feeding and insertion equipment for installing more than 100 fasteners per minute at least an order of magnitude faster than riveted or welded methods are also available.
