FAQs

The squeezing force on the fastener causes the sheet material beneath the head to cold flow into the back-tapered shank or undercut of the fastener securely locking it in place.

No, a self-clinching fastener must be installed using a squeezing action. A quick impact installation will not allow sufficient time for the sheet material to cold flow.

No. Self-clinching fasteners are installed using any type of parallel acting press which will squeeze the fastener in place.

No, the fastener does not deform in any way. There is no flaring, crimping, swaging, peening, or riveting necessary.

Thin sheet nuts, studs & standoffs can be used in sheets thinner than 1mm.

Blind rivet nuts, with knurled grip offer a higher torsional resistance to plain grip.

Stripping and re-plating is not recommended. Stripping a panel after plated fasteners are installed can damage the fastener. The recommended alternatives to this are the first choice – plate the panel and then install the plated fasteners. The second choice is – install un-plated fasteners into an un-plated sheet and then plate altogether.

The only self-clinching fasteners that will provide a complete water-tight seal are the M-CH line of concealed head studs and standoffs. These fasteners are clinched (pressed) into a blind hole, thereby keeping the reverse side of the sheet undisturbed and free of any voids that might allow any liquid to seep through.

No. All self-clinching fasteners are installed into a round punched or drilled hole. A hexagonal head will cause the sheet material to cold flow around the head to provide high torque-out resistance. The hex head will be flush in the sheet when installed.

Generally, there is no specified maximum thickness for sheets. However, because of their special design and function, a few fastener types do specify a thickness range which includes a maximum.

The self-clinching feature of a self-clinching fastener makes welding an unnecessary step. Self-clinching fasteners, when properly installed, have adequate holding power in the sheet without welding. In fact, self-clinching technology was originally conceived, and is, a less costly, cleaner and more dependable alternative to weld fasteners.

No. Typical torque-out values are generally quite high compared to the rotational force that will be put on them. In fact, for most quality self-clinching nuts, the screw will fail before the nut rotates in the material.

No, it has to be a hardened stainless steel.

Product code: Hardened stainless steel products can be identified when there is a '4' (400 series) i.e. M-SO4, M-BSO4

No, the blind rivet nuts or blind rivets are one of the few sheet metal products that can be installed from one side only.
