Stainless Steel Pan Head Phillips Self-Tapping Screws
304 and 316 stainless steel Phillips pan-head screws provide a sharp-point self-tapping fixing for sheet metal, ductwork and equipment assembly. The head bears above the surface, while full-length threads engage a correctly prepared receiving hole.
- 304 / 316 stainless steel
- Pan head with a broad bearing underside
- Sharp self-tapping point; A / AB types listed, drawing to confirm
KEY FEATURES & PERFORMANCE
Raised seating.
Sharp-point fixing.
Confirm the point and thread variant, prepared-hole size and receiving material before selecting dimensions. The Phillips pan head stays above the surface; check tool access and bearing area as well as the thread engagement in the assembly.
- 01
Grade selection for the exposure
304, often described as 18-8, is used for general exposure; molybdenum-bearing 316 is considered for salt or chemical conditions. Match the grade to the timber treatment or contact materials and environment.
- 02
A broad raised bearing face
The pan head spreads clamping force over the attached sheet or component. Its raised profile avoids a countersink but needs adequate head clearance.
- 03
Phillips tool compatibility
The cross recess accepts a matching Phillips bit or screwdriver. Correct size and alignment help maintain engagement and limit slipping during assembly.
- 04
Sharp-point self-tapping action
The source lists A / AB point forms. Confirm the exact geometry with the drawing and use the appropriate receiving hole; a sharp point is not a drill tip.
- 05
Threads along the shank
The full coarse thread engages the available substrate for clamp retention. Material, pilot size and engagement determine holding performance, not thread appearance alone.
- 06
Substrate-specific preparation
Sheet metal, aluminium, plastic and fibreglass respond differently to tapping. Match the hole, engagement and drive setting to the actual material and thickness.

APPLICATIONS & CONNECTION PLANNING
Connections This Range Is Made For
Sheet metal & ductwork
Review the pan-head bearing area and the thickness of the receiving sheet. The pilot hole and point form must suit the metal and screw configuration.
Equipment & marine assemblies
For general machinery and marine fittings, compare head clearance, access and exposure. Select the stainless grade and contact detail for the actual service conditions.
Aluminium, plastics & fibreglass
Identify the alloy, polymer or laminate and its thickness. Pilot preparation and trial assembly should address cracking, tapping resistance and required clamping.
Select against the actual materials, joint dimensions and exposure. Performance requirements need data for the ordered configuration and complete connection.
COATING SOLUTIONS
A Finish That Fits
the Project
Head colour matching, passivation and specialty finishes can be reviewed with your selected screw. Include the desired appearance and exposure conditions in the enquiry.
Specify the stainless grade, contact materials and environment alongside the finish. A decorative head colour and a protective surface treatment serve different purposes; coating scope and any test requirements are agreed for the exact configuration.

Product, OEM & Packaging Q&A
Product selection, configuration checks, custom production and packaging for this range.
Product
Does the sharp point eliminate the need for a hole?
Do not assume it does. This is a self-tapping screw, not a drill-point design. Establish the receiving-hole requirements for the material and thickness.
Product
Which point is supplied: Type A or Type AB?
Both names appear in the source description. The point geometry is confirmed on the drawing for the selected screw, rather than treating the names as one interchangeable configuration.
Product
How does it differ from the pan-head Type F screw?
This version has Phillips drive and a sharp tapping point. The Type F product has Torx drive and a blunt cutting end, with different prepared-hole and thread-cutting requirements.
OEM
Can you customise the screw design?
Yes. Head markings, head and drive details, dimensions and tolerances can be reviewed against your drawing or specified standard. A custom design is agreed separately from the pictured configuration.
OEM
Can you match the head colour or finish?
Yes. Share the target colour, appearance and exposure conditions. Head painting, passivation and specialty finishing requests are reviewed for the selected material and screw configuration.
OEM
Can we approve samples before full production?
Custom samples and initial inspection reports can be arranged before the production order. The sample scope, cost and timing are confirmed during development.
Packaging
Which pack formats can we request?
Options include small polybags, inner boxes and industrial bulk packing. State the order quantity, units and preferred pack count; the final packing quantity and carton size are agreed for the order.
Packaging
Can the packaging carry our brand?
Yes. Inner and outer boxes, printed logos and supplied artwork can be included in a private-label packaging brief. Artwork and print details are approved before production.
Packaging
Can you include barcodes and shipping marks?
Private labels, UPC / EAN barcodes, part numbers and shipping marks can be included. Provide the required identifiers and label artwork so they can be checked against the product and pack format.
ORDER SUPPORT
Documents, Production & Delivery
Material & inspection records
MTRs and mill certificates can be requested with the enquiry. Identify the material, order and document requirements so record scope and batch traceability can be agreed. Inspection reports are matched to the selected configuration.
Stock, bulk & custom orders
Available stock, bulk production and custom work follow different scheduling routes. Confirm availability for the exact configuration; quantities, specification and sample approval determine the quoted production and dispatch schedule.
International shipping
FOB, CIF or DDP terms can be reviewed for your destination, with shipment tracking arranged for the agreed route. Destination availability, duties, charges and delivery timing are confirmed in the quotation.
Standards & Material References
| Dimensional references | ASME B18.6.3 / ASME B18.2.1 / ANSI |
|---|---|
| Material / physical references | ASTM F593 (Group 1: 304/305; Group 2: 316) / ASTM A240 |
Source-listed references require confirmation of edition and component scope; specify the exact ANSI standard. The list is not a certificate or proof that every reference applies to this screw.
