NFHS-M3-6 Hex-Head Self-Clinching Stud, Stainless

Product Overview

The NFHS-M3-6 is a stainless steel hexagon-head self-clinching stud with an M3 x 0.5 external thread and a 6 mm stud length. It is designed for permanent press installation in a correctly prepared sheet hole, providing a fixed external thread with a compact hexagonal head on the installation side.

Part Number Breakdown

NFHS identifies the stainless steel hexagon-head self-clinching stud series. M3 identifies the M3 x 0.5 thread code, and 6 identifies the 6 mm stud length. Use the complete NFHS-M3-6 product number when requesting a quotation or confirming an order, because removing the N or changing the prefix identifies a different product family.

Installation and Sheet Requirements

Confirm the mounting-hole diameter and tolerance, sheet material and installation conditions using an installation drawing applicable to NFHS-M3-6 before preparing the panel. The catalog lists a minimum sheet thickness of 1.0 mm. Maintain at least 5.6 mm from the mounting-hole center to the sheet edge. Insert the stud into the prepared hole and use compatible self-clinching press tooling with flat, parallel squeezing force until the seating feature is fully installed.

Do not install the stud by impact. Burrs, an incorrect hole diameter, insufficient edge distance or nonparallel pressing can affect seating and retention. Confirm sheet material, hardness, tooling and press conditions against the approved installation instruction before production.

Material and Finish

The NFHS model is identified as stainless steel in the catalog. The exact page does not assign a stainless steel grade or a separate surface finish to NFHS-M3-6. Any alloy-grade, passivation, appearance, corrosion or documentation requirement should therefore be stated in the approved order rather than inferred from the product photograph or an external supplier page.

Selection and Related Variants

Select NFHS-M3-6 when the required configuration is a stainless steel hexagon-head self-clinching stud with M3 x 0.5 thread and 6 mm length. On the same catalog page, NFH identifies the carbon steel version and NFHS identifies the stainless steel version. The page also lists M4, M5, M6 and M8 thread rows with their own installation dimensions. Do not substitute another prefix, thread code or length without reviewing the exact catalog entry.

Use Conditions

This stud is intended for sheet assemblies that require a permanently installed external M3 threaded mounting point and a hexagonal head on the installation side. Suitability depends on sheet material, sheet thickness, hole preparation, edge distance, installation tooling and the required material or finish documentation.

Ordering Information

For quotation or order confirmation, provide NFHS-M3-6, required quantity, sheet material and thickness, mounting-hole preparation, required stainless steel grade or finish documentation, packaging requirements and inspection requirements. Confirm current stock, price, minimum order quantity and lead time for each order.

Frequently Asked Questions

What does NFHS-M3-6 identify?

NFHS-M3-6 identifies an NFHS-series stainless steel hexagon-head self-clinching stud with an M3 x 0.5 thread and a 6 mm stud length. Use the complete product number because FHS-M3-6 and other similar prefixes identify different head structures or product families.

How should the mounting-hole dimensions be confirmed?

M3 x 0.5 specifies the external machine thread, not the mounting-hole diameter or tolerance. Before preparing the panel, use an installation drawing applicable to NFHS-M3-6 to confirm the hole dimensions, sheet material and thickness, and installation conditions. Do not determine the mounting hole from the M3 thread designation alone.

What sheet thickness and edge distance are required?

The catalog specifies a minimum sheet thickness of 1.0 mm and a minimum edge distance of 5.6 mm from the mounting-hole center to the sheet edge. Confirm the mounting-hole diameter and tolerance, selected sheet material and installation conditions using an installation drawing applicable to NFHS-M3-6 before production.

How should NFHS-M3-6 be installed?

Install NFHS-M3-6 by pressing it into the correctly prepared sheet hole with compatible self-clinching tooling and flat, parallel squeezing force. Do not use impact installation. Verify seating and retention on an approved first article with the selected sheet material and production tooling.

What material and finish are specified for NFHS-M3-6?

The NFHS model is specified as stainless steel. The catalog page does not state a stainless steel grade or separate surface finish for NFHS-M3-6, so any alloy, passivation, appearance or documentation requirement must be included in the approved order.

What is the difference between NFH and NFHS models?

The catalog identifies NFH as the carbon steel model and NFHS as the stainless steel model. Keep the complete NFHS-M3-6 number when stainless steel is required, and confirm any grade or finish requirement separately because the page does not assign those details.
