DBSO-M3-4 Blind Threaded Standoff with Serrated Base

Product Overview

The DBSO-M3-4 is a serrated blind threaded self-clinching standoff for sheet-metal assemblies. Its cylindrical body contains a blind M3 internal thread, while the serrated clinch base engages the panel during controlled press installation. The closed-end design provides a reusable female thread without allowing the mating screw to pass through the bottom of the standoff.

Product Identification

Use the complete product number DBSO-M3-4 when requesting a quotation or placing an order. DBSO identifies the serrated blind threaded standoff series, M3 identifies the internal thread code, and 4 identifies the length code. Exact dimensional limits must follow the approved DBSO-M3-4 drawing or purchase specification.

Installation Guidance

Prepare the round mounting hole and confirm the panel thickness according to the approved product drawing. Insert the serrated clinch end squarely into the hole. Apply controlled parallel squeeze force with suitable installation tooling until the standoff is fully seated. Inspect head seating, panel distortion, rotational resistance and the M3 thread after installation. Do not substitute impact installation for the specified press process.

Material and Finish Control

Material, hardness, plating and corrosion-protection requirements must match the approved DBSO-M3-4 purchase specification. Any coating must remain compatible with the M3 thread and the serrated clinch features.

Selection and Ordering

Select DBSO-M3-4 when an assembly requires a blind M3 female thread, a serrated anti-rotation base and press installation in sheet metal. For quotation and order confirmation, provide the complete product number, quantity, panel material and thickness, approved mounting-hole specification, finish requirement, packaging requirement and any inspection or compliance documents.

Frequently Asked Questions

What does DBSO-M3-4 identify?

DBSO-M3-4 identifies the DBSO serrated blind threaded standoff series, the M3 internal thread code and length code 4. Use the complete product number because each code segment selects a specific configuration.

Why use a blind threaded standoff?

A blind threaded standoff provides a closed-end female thread. It helps control screw penetration and supports assemblies where a through-threaded body is not suitable.

What does the serrated base do?

The serrated clinch base engages the panel during press installation and helps resist rotation in service. Performance depends on the approved hole size, panel material, panel thickness and installation force.

How is DBSO-M3-4 installed?

Place the serrated end in the prepared round hole and apply controlled parallel press force with suitable tooling. Follow the approved product drawing for hole size, sheet thickness and seating requirements, then inspect the installed thread and panel.

What information should be supplied when ordering?

Provide DBSO-M3-4, quantity, panel material and thickness, mounting-hole specification, finish requirement, packaging requirement and any inspection or compliance documents. Confirm current stock, price, minimum order quantity and lead time for the order.
