FASTEKS® Filko – Blind Rivet Nuts

FASTEKS^® FILKO is a single-piece, through-threaded, one-sided application nut, which is ‘blindly’ installed without re-work. It is an efficient solution for installing captive threads, even if there is no access to the backside of the panel. It can provide a resilient thread, particularly on thin-walled components and hollow sections. The rivet beading will ensure a high tear-out strength. FASTEKS^® FILKO blind rivet nuts come in three major types of shanks; round shank, knurled shank and hexagonal shank.

Features:

One-sided installation
Multiple applications, either as a blind rivet nut or blind rivet screw
High tear-out strength as result of rivet beading
Possible to assemble in surface-treated parts
Wide range of head styles and materials
Rational installation with manual rivet gun or hydro-pneumatic tools
Stable grip force

Round Shank
Features

A round-shank blind rivet nut is very commonly used in general applications. Several head styles, end styles, and materials in different sizes are available.

Head style: Flat head / Flush head / Countersunk head 90º
End style: Open end / Closed end
Material: Steel with zinc plate, thick passivated (RoHs), Stainless steel A2, A4
Thread size: M3-M4-M5-M6-M8-M10-M12 (Stainless steel A4 from M4 to M8) Inch sizes available upon request

Knurled Shank
Features

For anti-torque requirements, a blind rivet nut with knurled shank may be the best solution for materials softer than the fastener.

Head style: Flat head / Flush head / Countersunk head 90º
End style: Open end / Closed end
Material: Steel with zinc plate, thick passivated (RoHs), Stainless steel A2, A4
Thread size: M3-M4-M5-M6-M8-M10-M12 (RPoly, AVRKS, RC from M4 to M8) Inch sizes available upon request.

Hexagonal Shank
Features

A hexagonal shank will improve torque-out resistance when installed into a hexagonal hole.

Head style: Flat head / Flush head
End style: Open end / Closed end
Material: Steel with zinc plate, thick passivated (RoHs), Stainless Steel A2, A4
Thread size: M3-M4-M5-M6-M8-M10-M12 (HEXPoly, AVHEXKS, A4 Stainless steel made from M4-M8) Inch sizes available upon request.

Blind Rivet Screw
Features

With a body like a blind rivet nut, but with high-strength male threads, blind rivet screws allow for flexibility in manufacturing. A special nose piece is required to install these fasteners.

Head Style: Flat head / Countersunk head
Shank style: Hexagonal shank / knurled shank
Material: Steel with zinc plate, thick passivated (RoHs)
Thread size: M5-M6-M8. Inch sizes available upon request.

Blind Clip-In Nut
Features

The flat head blind clip-in nut can be installed with a standard screw driver. It can dampen shock and vibration in an assembly. A brass insert nut is embedded in the neoprene body, which can be used for thermal or electrical insulation.

Head Style: Flat head / Large flat head
Material: thread insert nut of brass, body of neoprene
Thread size: Flat head M3-M4-M5-M6-M8 / Large flat head M3-M4-M5-M6
