Product Overview
The AS-M3-1 is a non-locking steel floating self-clinching nut with an M3 x 0.5 internal thread. It is designed for installation in sheet metal where a permanent captive thread and limited alignment compensation are required. The floating inner nut helps the mating screw engage when the mating hole is not perfectly aligned, while the self-clinching body remains fixed in the panel.

Part Number Breakdown
The designation AS-M3-1 identifies the exact catalog configuration. AS is the product code for the non-locking steel version. M3 is the thread code, corresponding to an M3 x 0.5 thread. The final 1 is the shank code and identifies the version for a minimum sheet thickness of 1.0 mm. Use the complete part number when requesting a quotation or confirming interchangeability.
Installation and Panel Preparation
Prepare the mounting hole to the catalog value and keep the fastener and panel surfaces clean. Place the fastener squarely in the hole and apply a controlled parallel pressing force so the clinching feature seats uniformly. Do not install the part by impact or by tightening a screw through it. Maintain the stated minimum edge distance from the hole center to the panel edge. After installation, verify seating, thread condition, panel flatness and the movement of the floating inner nut.
Material and Finish
The catalog identifies AS-M3-1 as the steel, non-locking version. Use the complete part number when ordering, and state any required finish or compliance documentation separately on the purchase order.
Selection and Ordering
Select this model only when the assembly requires an M3 x 0.5 floating captive thread and the panel meets the 1.0 mm minimum thickness requirement. Check the 7.37 mm installation hole, 7.62 mm minimum edge distance and available installation clearance against the drawing. For quotation and order confirmation, provide the full part number AS-M3-1, required quantity, panel material and hardness, finish requirement, inspection requirements and any applicable drawing or industry standard.
