M4x10 Open-end rivet nuts AN 310 A2 smooth 5 pcs.

Open-end rivet nuts AN 310 — M4 × 10 mm, A2, 5 pieces

The rivet nut allows an internal thread to be set in a thin component using a rivet-nut tool. It has a smooth cylindrical body, through hole and a cylindrical, and.e. flat, flange. The knurling is beneath the flange and limits rotation of the item; the outer surface of the long body remains smooth. AN 310 is the catalogue designation of this design.

Dimensions come from column M4 for the stainless version in the AN 310 data sheet dated 20.02.2017. Length l = 10 mm excludes flange k = 1 mm. Material A2 has been retained according to the existing offer; no unconfirmed EN grade number has been assigned. The data sheet gives no dimensional tolerances or coating for this version — these fields remain to be confirmed. No unstated thread class, torque, setting force or load capacity has been added.

Grip range and installation hole

For this version, g = 0,25–3,00 mm denotes the material thickness range in which the item can be set. Recommended hole according to the data sheet: 6,1 mm. The range and hole are marked as manufacturer data in the data sheet. Trials on the intended material are required for proper rivet-nut and setting-parameter selection.

After setting, the deformable body section clamps the material between the flange and the formed bulge. The rivet nut is open-end; it does not provide a sealed closure. Setting parameters depend on the tool and material used.

Frequently asked questions

How many rivet nuts does the price cover?

The price covers a pack of five pieces.

Does the dimension 10 mm include the flange?

No. Body length l = 10 mm is measured beneath the flange; its thickness k is 1 mm.

Is the body knurled?

The long body is smooth. The AN 310 data sheet specifies knurling on the surface beneath the flange to prevent rotation.

What hole and material thickness does the data sheet specify?

For stainless M4, a hole of 6,1 mm and grip range of 0,25–3,00 mm are specified. Selection and setting parameters must be confirmed by a trial on the intended material.
