Stainless Steel Torx Washer Head Self-Tapping Screw for Lighting Fixtures

Product Overview

Stainless Steel Torx Washer Head Self-Tapping Screw for Lighting Fixtures is presented as a self-tapping screw for lighting-fixture assembly. The purchasing distinction is its integral washer head, six-lobe drive 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 Self-Tapping 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 integral washer head, six-lobe drive 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 thin housings and brackets, restricted tool access and appearance around the installed head for the intended lighting-fixture assembly.
• Inspection: Identify the dimensions and functions that are critical to the self-tapping screw, together with gauges, reports, sampling level and packaging protection.

Typical Applications

• Sheet-metal, plastic or pre-drilled component assembly
• Lighting, appliance, enclosure and equipment manufacturing
• OEM joints requiring thread formation during installation

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

• Six-lobe drive
• Assembled washer interface
• Self-tapping thread and point
• 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 shoulder or pin diameter, concentricity and step length, thread engagement, and burr and edge 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 Torx Washer Head Self-Tapping Screw for Lighting Fixtures, send a dimensioned drawing or marked sample showing the standard reference, material/grade, size notation, thread data where applicable, integral washer head, six-lobe drive and threaded body or point, finish and packaging. Also identify thin housings and brackets, restricted tool access and appearance around the installed head because these points affect suitability for lighting-fixture assembly. Any unmarked dimension remains subject to technical clarification before tooling or production.

Customization & Order Information

Frequently Asked Questions

Which interface dimensions should be controlled on this self-tapping screw?

Confirm the integral washer head, six-lobe drive 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.

Which application details should accompany the RFQ?

Describe thin housings and brackets, restricted tool access and appearance around the installed head. These details help determine whether the proposed geometry and material suit lighting-fixture assembly.

Which dimensions are needed to quote this self-tapping 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.
