Technical FAQ – Straight Knurled Brass Inserts

Which material should be specified?

Specify the brass alloy and condition on the drawing. Free-machining and forging brasses are different choices; steel or stainless steel parts are separate material options, not brass grades. Confirm corrosion and strength requirements for the application.

How do I confirm connection compatibility?

Specify the internal thread and the external retention profile, including knurl, undercuts and installation method. For BSP/NPT inserts, identify BSPP or BSPT explicitly; NPT and BSP threads have different forms and must not be interchanged.

What dimensions are needed for selection?

Provide the insert drawing, thread, host material, boss geometry, pilot-hole dimensions and installation method. Pull-out and torque resistance depend on the host material and assembled design.

What determines suitability and operating limits?

Threaded inserts provide a durable thread in a suitable host material. Moulded-in, press-in and heat-installed designs are not automatically interchangeable. Confirm retention performance by testing the intended assembly.

What finish and inspection documentation should I request?

State the required surface finish, coating thickness where relevant, and critical dimensions on the order. Material certificates, dimensional reports and any specified performance tests should be agreed in the quotation. A reference to a standard is not a declaration of third-party certification.

Can I request a custom part or export quotation?

Send a drawing or clearly dimensioned sample specification, material, quantity and delivery destination. Identify application conditions and required approvals. Brass Parts India can review the requirement and confirm feasibility, price, documentation and lead time for the quoted part.
