Chicago Round Flat Head Screw

Product Overview

Chicago Round Flat Head Screw is presented as a custom fastener for furniture and panel assembly. The purchasing distinction is its flat bearing head, drive or wrenching feature shown on the approved drawing and threaded body or point and the way those features engage the mating parts. The reference photographs support identification; production remains subject to an approved drawing, sample or standard.

Selection and RFQ Notes for This Custom Fastener

Industrial product catalogues commonly separate comparable parts by standard, material/grade, diameter × length, pitch, thread coverage, head/drive and pack quantity. For this page those fields are treated as RFQ inputs, not assumed stock specifications.

• Size callout: State diameter × overall length, pitch, threaded length or grip length, and every non-standard shoulder, collar or bore dimension.
• Interface geometry: Confirm the flat bearing head, drive or wrenching feature shown on the approved drawing and threaded body or point, together with the mating-part dimensions and any installation clearance limit.
• Material condition: Specify carbon steel, stainless steel or another specified alloy; final grade is drawing-controlled; do not use the word “stainless” or “high strength” as the only acceptance requirement.
• Installation fit: Review surface appearance, panel thickness and repeatable dismantling or service access for the intended furniture and panel assembly.
• Inspection: Identify the dimensions and functions that are critical to the custom fastener, together with gauges, reports, sampling level and packaging protection.

Typical Applications

• Furniture, cabinet and panel joining
• Removable display, leather or document assemblies
• OEM structures requiring a neat, low-profile connection

Application suitability depends on the final material grade, dimensions, mating parts, installation method, load and service environment. Please share assembly details for engineering review.

Drawing-Controlled Structure and Key Features

• Flat head profile
• Drawing-controlled dimensions, tolerances and thread engagement
• Material, finish and inspection plan configured for the application

The visible features shown in the photos support RFQ review, while the approved drawing, standard and agreed inspection criteria remain the controlling production documents.

Quality Inspection Process

The control plan should follow the buyer’s critical-to-function dimensions and the agreed sampling level. Typical checkpoints are overall length, thread gauge result, head and drive geometry, and surface condition. Certificates or special reports are supplied when they are included in the quotation.

• Material and surface-condition verification
• Critical-dimension and tolerance inspection
• Thread gauge, head and drive geometry checks
• Final appearance, count and packaging inspection

Optical / Vision Sorting Inspection

For suitable higher-volume orders, optical or vision sorting can be evaluated for measurable and visible characteristics such as overall profile, head presence, length, drive condition and selected surface defects. The approved drawing and agreed functional tests remain the acceptance criteria.

Drawing and Customization Requirements

For Chicago Round Flat Head Screw, send a dimensioned drawing or marked sample showing the standard reference, material/grade, size notation, thread data where applicable, flat bearing head, drive or wrenching feature shown on the approved drawing and threaded body or point, finish and packaging. Also identify surface appearance, panel thickness and repeatable dismantling or service access because these points affect suitability for furniture and panel assembly. Any unmarked dimension remains subject to technical clarification before tooling or production.

Customization & Order Information

Frequently Asked Questions

Can Hongyuan manufacture from a physical sample?

Yes. A sample supports identification and reverse review, but a drawing or signed dimensional report should define the final acceptance criteria.

How are MOQ and lead time established?

They are quoted after material availability, forming or machining route, tooling, inspection level, finish, packaging and order quantity have been reviewed.

Which application details should accompany the RFQ?

Describe surface appearance, panel thickness and repeatable dismantling or service access. These details help determine whether the proposed geometry and material suit furniture and panel assembly.

Which dimensions are needed to quote this custom fastener?

Provide diameter, overall length, pitch, thread or grip length, head dimensions and every shoulder, collar, bore or point dimension that affects the mating parts.

How should the material grade be specified for furniture and panel assembly?

State the required grade or alloy, mechanical condition, corrosion exposure and certificate requirement. The current material scope is carbon steel, stainless steel or another specified alloy; final grade is drawing-controlled.
