M2.5-11 CPCI Captive Panel Screw, Stainless Steel

Product Overview

The M2.5-11 is a CPCI captive panel screw with an M2.5 thread and an 11 mm screw length. The LAMBOOR catalog presents the product as a stainless steel screw used with a copper sleeve cap for retained fastening in chassis and front-panel assemblies.

The captive construction keeps the fastener associated with the panel after release, helping prevent loose hardware during access and servicing.

Designation Breakdown

M2.5 identifies the metric thread size and 11 identifies the catalog-listed screw length in millimeters. CPCI is the product-family heading used in the catalog.

Use the complete M2.5-11 designation together with the CPCI captive-panel-screw description when requesting a quotation or confirming an order.

Installation and Panel Requirements

Use the stainless steel M2.5 x 11 screw with the matching copper sleeve or cap arrangement shown in the approved catalog drawing. The catalog also identifies an M2.5 threaded hole.

Confirm the panel construction, sleeve orientation, mating thread, retained travel and installation method against the approved sample or assembly drawing before production. Do not apply the sleeve dimensions to the screw body or substitute another retainer style without an engineering check.

Material and Finish

The catalog identifies the screw as stainless steel and the sleeve or cap as copper. It does not assign a stainless steel grade, copper grade or separate surface finish to this entry.

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

Selection and Related Components

Select M2.5-11 when the required fastener uses an M2.5 thread, an 11 mm screw length and the corresponding CPCI captive arrangement.

The catalog page shows several assembled configurations, so the buyer should specify whether the order requires the stainless steel screw only or the complete screw-and-sleeve assembly. Do not assume that another knob, sleeve or retainer shown on the page is interchangeable.

Use Conditions

This captive panel screw is intended for chassis or front-panel assemblies that require a retained hand-operated fastener. Suitability depends on the panel geometry, matching M2.5 thread, sleeve configuration, retained travel and approved assembly drawing.

Ordering Information

For quotation or order confirmation, provide M2.5-11, quantity, whether the screw only or complete captive assembly is required, panel details, mating thread, sleeve or cap configuration, required finish, packaging and inspection documentation.

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

Frequently Asked Questions

What does M2.5-11 identify?

M2.5-11 identifies the catalog-listed M2.5 thread and 11 mm screw length for this CPCI captive panel screw. Include both the M2.5-11 designation and the CPCI product description in a quotation request so the required fastener family is clear.

Is M2.5-11 supplied as a screw or a complete captive assembly?

The catalog presents an M2.5 x 11 stainless steel screw together with a copper sleeve or cap arrangement. Because the product image may show an individual component, state whether the order requires the screw only or the complete screw-and-sleeve assembly.

Which materials are specified?

The catalog specifies stainless steel for the screw and copper for the sleeve or cap. It does not state the exact material grades or a separate finish, so any grade, passivation, plating, appearance or documentation requirement must be written into the approved order.

Which dimensions belong to the sleeve or cap?

The catalog drawing lists 5.29 and 6.00 mm cap widths, a 5.90 mm sleeve collar width, an 8.00 mm sleeve base width, a 0.30 mm shoulder height, a 3.20 mm retainer neck width and a 1.40 mm retainer neck height. These values describe the illustrated sleeve or cap geometry and should not be treated as screw-body dimensions.

What information should be supplied when ordering?

Provide M2.5-11, quantity, screw-only or complete-assembly requirement, panel details, mating M2.5 thread, sleeve configuration, finish, packaging and inspection documentation. Confirm current stock, price, minimum order quantity and lead time for the specific order.
