BNS-M3-1 Hex Self-Clinching Nut, Stainless Steel

Product Overview

The BNS-M3-1 is a stainless steel hex self-clinching nut with an M3 x 0.5 internal thread. It creates a permanent reusable female thread in sheet metal through press installation. The hexagonal body and serrated clinching section provide mechanical engagement with the panel while the internal thread remains accessible for repeated assembly.

Part Number Breakdown

Use the complete product number BNS-M3-1 when requesting a quotation or placing an order. BNS identifies the stainless steel hex self-clinching nut series, M3 identifies the thread code, and 1 identifies the clinching shank configuration for a minimum sheet thickness of 1 mm.

Installation and Panel Requirements

Prepare a 4.5 mm mounting hole and maintain at least 5.6 mm from the hole center to the panel edge. Position the clinching section in the prepared hole with the nut square to the sheet. Apply a controlled parallel pressing force until the clinching shoulder is fully seated against the panel. Keep the mounting hole free of burrs and contamination, and avoid impact installation or uncontrolled over-pressing that could distort the sheet or thread.

Material and Construction

The BNS series uses stainless steel construction. The hexagonal wrenching body, M3 through thread and serrated clinching section form a compact captive-thread solution for sheet metal. Confirm compatibility between the fastener hardness and panel material before installation, and protect the thread and clinching section from contamination during handling.

Selection and Ordering

Select BNS-M3-1 when the assembly requires an M3 x 0.5 captive female thread in sheet metal with a minimum thickness of 1 mm. Confirm the 4.5 mm installation hole, the 5.6 mm minimum edge distance and available clearance for the hexagonal body before release. For quotation and order confirmation, provide the complete product number, required quantity, panel material and thickness, and any required inspection or compliance documentation. Stock, price, minimum order quantity and lead time should be confirmed for the current order.
