Technical FAQ – Brass Machine Screws

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 thread diameter, pitch, tolerance class and engagement length, together with the head or nut form. Metric and imperial threads are different systems. Use the applicable dimensional standard or an agreed drawing; a list of standards does not establish compliance for every variant.

What dimensions are needed for selection?

Provide a dimensioned drawing, mating-thread details, length or thickness, head dimensions, finish and quantity. Agree critical tolerances and inspection requirements before production.

What determines suitability and operating limits?

Brass fasteners serve mechanical, electrical and decorative assemblies where the selected grade is suitable. Permitted load and tightening torque depend on alloy, geometry, thread engagement and lubrication. Do not apply steel fastener property classes or torque tables to brass without an engineering assessment.

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.
