Stainless Steel Extra-Long Slotted Countersunk Machine Screw for Sanitary Ware

Product Overview

Stainless Steel Extra-Long Slotted Countersunk Machine Screw for Sanitary Ware is presented as a machine screw for sanitary-ware hardware. The purchasing distinction is its flush countersunk head, straight slot 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 Machine Screw

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 flush countersunk head, straight slot and threaded body or point, together with the mating-part dimensions and any installation clearance limit.
• Material condition: Specify stainless steel; grade such as 304 or 316 must be selected against the service environment; do not use the word “stainless” or “high strength” as the only acceptance requirement.
• Installation fit: Review moisture exposure, visible-head finish and fit with ceramic or metal hardware for the intended sanitary-ware hardware.
• Inspection: Identify the dimensions and functions that are critical to the machine screw, together with gauges, reports, sampling level and packaging protection.

Typical Applications

• Industrial machinery and equipment assembly
• Automotive, appliance, electronics or enclosure manufacturing
• Custom OEM projects produced from a drawing or verified sample

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

• Slotted drive
• Countersunk head profile
• Extended-length body
• 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

Inspection is built around the drawing characteristics that affect assembly, not a generic cosmetic checklist. 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 Stainless Steel Extra-Long Slotted Countersunk Machine Screw for Sanitary Ware, send a dimensioned drawing or marked sample showing the standard reference, material/grade, size notation, thread data where applicable, flush countersunk head, straight slot and threaded body or point, finish and packaging. Also identify moisture exposure, visible-head finish and fit with ceramic or metal hardware because these points affect suitability for sanitary-ware hardware. Any unmarked dimension remains subject to technical clarification before tooling or production.

Customization & Order Information

Frequently Asked Questions

Which dimensions are needed to quote this machine screw?

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 sanitary-ware hardware?

State the required grade or alloy, mechanical condition, corrosion exposure and certificate requirement. The current material scope is stainless steel; grade such as 304 or 316 must be selected against the service environment.

Which interface dimensions should be controlled on this machine screw?

Confirm the flush countersunk head, straight slot and threaded body or point, 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.
