Rivetto cieco GESIPA 6310931 acciaio/acciaio 5×12 mm testa piatta per 6,0–8,5 mm

Blind rivet GESIPA 6310931 is a steel body with a steel mandrel flat-head fastener featuring a 5×12 mm profile and a working grip range of 6.0–8.5 mm. Designed for blind joining where access is available only from one side, this rivet forms a permanent, vibration-resistant joint and leaves a low-profile, flush finish on the visible side. It is suited for applications in metal fabrication, HVAC installations, enclosures and general assembly where a reliable mechanical connection is required.

Advantages

The all-steel construction ensures strength and good shear and tensile performance for general-purpose fastening. The flat head produces a flush, neat surface that reduces snagging and allows for compact assemblies. The blind installation method enables fastening where the rear side is inaccessible, while the specified grip range accommodates moderate material thicknesses for overlap joints. The rivet provides consistent setting characteristics and is compatible with common blind rivet tools designed for steel rivets.

Suitable for

• Joining sheet metal overlaps in metal fabrication
• Securing HVAC ductwork and fittings
• Assembling enclosures, panels and cabinets
• General industrial and maintenance fastening where single-side access is required

Key specifications

• Material: steel body and steel mandrel
• Head style: flat head for a flush finish
• Body size: 5×12 mm
• Working grip range: 6.0–8.5 mm
• Fastening type: blind rivet (single-side installation)

How to use

Drill or prepare a hole matching the rivet body diameter, insert the blind rivet through the aligned parts, and use a compatible rivet tool to set the mandrel until the head deforms and the blind-side bulge forms. Continue pulling until the mandrel snaps, leaving the swaged body securing the materials. Verify that the head sits flush and that the joint feels secure; trim or remove any protruding mandrel remnants as required by the tool's setting method.

Recommendations

For best results, select a rivet diameter and hole tolerance matching the 5 mm body size and use a rivet tool rated for steel mandrels. Pre-drill holes to appropriate tolerances, ensure parts are clamped or aligned before setting, and avoid overloading the joint beyond the rivet's material strength. In corrosive environments consider alternative materials or protective coatings appropriate to the application.
