FHS-M3-6 Self-Clinching Stud, Stainless Steel

Product Overview

The FHS-M3-6 is a stainless steel flush-head self-clinching stud with an M3 x 0.5 thread and a 6 mm stud length. Its flat round head and under-head clinching features are designed for press installation into a prepared sheet hole, creating an externally threaded mounting point while keeping the head side flush.

Part Number Breakdown

FHS identifies the stainless steel self-clinching stud series, M3 identifies the metric thread code and 6 identifies the stud length. Use the complete FHS-M3-6 product number for quotation and order confirmation.

Installation and Sheet Requirements

Prepare a 3.0 mm mounting hole in sheet material at least 1.0 mm thick, and maintain at least 5.6 mm from the hole centerline to the sheet edge.

Install the stud with compatible self-clinching press tooling and a parallel pressing force so the head seats flush against the sheet. The mating or attached part should use a hole no larger than 3.6 mm where this catalog limit applies.

Confirm panel material, hardness, tooling and press conditions against the approved installation instruction before production.

Material and Finish

The FHS prefix identifies the stainless steel model in this family. The catalog does not assign a separate surface finish to the FHS-M3-6 row.

Any passivation, appearance or documentation requirement should therefore be stated on the approved order rather than inferred from the product photograph.

Selection and Related Variants

Select FHS-M3-6 when the required configuration is a stainless steel flush-head self-clinching stud with M3 x 0.5 thread and 6 mm length.

The same catalog family uses FH for steel and FHA for aluminum models, while the thread and length segments change with the required size. Do not substitute a related prefix or length without checking the material and assembly requirements.

Use Conditions

This stud is intended for sheet assemblies that need a permanently installed external M3 threaded mounting point and a flush head on the installation side.

Suitability depends on the sheet material, thickness, mounting-hole preparation, edge distance and approved press tooling.

Ordering Information

For quotation or order confirmation, provide FHS-M3-6, quantity, sheet material and thickness, mounting-hole preparation, attached-part hole requirement, required finish, packaging and inspection documentation.

Confirm current stock, price, minimum order quantity and lead time for each order.

Frequently Asked Questions

What does FHS-M3-6 identify?

FHS-M3-6 identifies an FHS-series stainless steel flush-head self-clinching stud with an M3 x 0.5 thread and a 6 mm stud length. Use the complete product number when requesting a quotation or confirming an order.

What sheet thickness and mounting hole are required?

The catalog specifies a minimum sheet thickness of 1.0 mm and a 3.0 mm mounting hole. Maintain the listed 5.6 mm minimum edge distance and verify the sheet material, hardness and approved installation instruction before production.

Why are both 3.0 mm and 3.6 mm hole sizes listed?

The 3.0 mm value is the mounting hole used to install the stud in the base sheet. The 3.6 mm value is the maximum hole size in the attached or mating part. These two requirements serve different parts of the assembly and should not be interchanged.

What material and finish are specified?

The FHS model is specified as stainless steel. The catalog row does not state a separate surface finish for FHS-M3-6, so any passivation, appearance or documentation requirement should be written into the approved order instead of being inferred from the photograph.

What information should be supplied when ordering?

Provide FHS-M3-6, quantity, sheet material and thickness, mounting-hole preparation, attached-part hole requirement, required finish, packaging and inspection documentation. Confirm current stock, price, minimum order quantity and lead time for the specific order.
