Flange Bolt

Product Overview

This flange bolt is intended for buyers comparing geometry, assembly fit and material choice for OEM machinery and equipment assembly. Its configuration is defined by the integral flanged head, wrenching feature, shank or grip section and external thread. Before quotation, Hongyuan checks mating-part material, joint load and service environment and installation tool and access rather than assuming a catalogue size from the image.

Selection and RFQ Notes for This Flange Bolt

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 integral flanged head, wrenching feature, shank or grip section and external thread, 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 mating-part material, joint load and service environment and installation tool and access for the intended OEM machinery and equipment assembly.
• Inspection: Identify the dimensions and functions that are critical to the flange bolt, together with gauges, reports, sampling level and packaging protection.

Typical Applications

• Machinery, equipment and fabricated-frame assembly
• Structural, automotive and industrial component fastening
• OEM joints requiring removable high-strength clamping

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

• Integrated flange bearing face
• 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 Flange Bolt, send a dimensioned drawing or marked sample showing the standard reference, material/grade, size notation, thread data where applicable, integral flanged head, wrenching feature, shank or grip section and external thread, finish and packaging. Also identify mating-part material, joint load and service environment and installation tool and access because these points affect suitability for OEM machinery and equipment assembly. Any unmarked dimension remains subject to technical clarification before tooling or production.

Customization & Order Information

Frequently Asked Questions

How should the material grade be specified for OEM machinery and equipment 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.

Which interface dimensions should be controlled on this flange bolt?

Confirm the integral flanged head, wrenching feature, shank or grip section and external thread, mating-part dimensions, assembly clearance and any functional gauge or installation test. These points should be identified on the drawing.

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 mating-part material, joint load and service environment and installation tool and access. These details help determine whether the proposed geometry and material suit OEM machinery and equipment assembly.

Request a Quote

To quote Flange Bolt, send the target quantity, dimensioned drawing or sample, material/grade, finish, inspection and packaging requirements, and delivery destination. For a flange bolt used in OEM machinery and equipment assembly, please also identify mating-part material, joint load and service environment and installation tool and access. Hongyuan will confirm manufacturability and commercial terms against the approved specification.
