#10 × 1 in · Integrated hex washer head
Stainless Steel #10 × 1 in Hex Head Self-Drilling Screws
This #10 × 1 in screw combines an external hex drive, an integral bearing flange and a self-drilling point. The nominal size is approximately 4.8 × 25 mm in the source specification, for selected metal-to-metal and equipment connections.
- #10 × 1 in; source nominal size approximately 4.8 × 25 mm
- Integrated flange with external hex socket drive
- Heat-treated 410, 304 or 316 stainless steel
KEY FEATURES & PERFORMANCE
A defined size.
A broad hex flange.
The integrated washer face distributes clamping contact without a separate flat bearing washer. Full-length tapping threads and a Tek point address the receiving support. The flange is a bearing feature; a weather seal requires its own specified assembly.
- 01
Material choices for the connection
Heat-treated 410 offers a harder option; 304 and 316 address different exposure requirements. Consider 316 for salt or chemical exposure. The chosen material, point construction and support must be assessed together.
- 02
Defined #10 × 1 in format
The product is identified by its #10 gauge and 1 in length. The source’s 4.8 × 25 mm notation is approximate; the ordered drawing establishes nominal dimensions, measuring method and tolerances.
- 03
Integrated bearing flange
The broad underside distributes contact pressure over the sheet or fitting. It provides a bearing face, but does not by itself create a sealed or waterproof penetration.
- 04
External hex drive
A matching six-point socket or nut setter engages the head for torque transfer. Socket clearance and a controlled stopping point support proper seating without relying on excessive tightening.
- 05
Self-drilling Tek point
The cutting tip opens the receiving metal before the tapping thread follows. The selected material, point geometry, steel grade and thickness determine drilling suitability.
- 06
Full-length tapping thread
Continuous tapping threads engage the support along the available shank. Effective thread engagement and the complete joint govern holding performance; thread form alone does not establish a vibration or load rating.

APPLICATIONS & CONNECTION PLANNING
Connections & Selection Details
Sheet metal & steel joists
Heavy-gauge sheet metal and steel joists are listed uses. Establish the exact layer build-up, receiving thickness and grade, then match the point and available engagement to the fixing schedule.
HVAC & equipment
Equipment housings and HVAC parts need socket access and adequate bearing around the hole. Check internal tip clearance and any vibration requirements with the data for the actual connection.
Roofing & cladding
The flange can bear against roofing or cladding components, but exposed penetrations may need a separate sealing detail. Identify sheet profile, support thickness and weathering requirements in the specification.
Use the fixing schedule and data for the selected fastener and joint. Published applications do not establish a rated load or universal installation method.
COATING SOLUTIONS
A Finish for
the Connection
Ruspert is a listed option for this product range. Head colour matching, passivation and specialty finishes can also be reviewed through the custom-order process.
Select the finish with the stainless steel grade, receiving material and environment. Include contact metals, exposure, colour and any test requirement in the specification. Availability and test documentation apply to the agreed configuration; no salt-spray duration is inferred from another product.

Product, OEM & Packaging Q&A
Product selection, custom production and packing details for this screw design.
Product
What does #10 × 1 in mean here?
It identifies the nominal gauge and inch length. The source lists approximately 4.8 × 25 mm; 25 mm is not an exact conversion of 1 in. The final drawing defines the dimensions and tolerances.
Product
Is the integrated washer face weather-sealing?
It is a metal bearing flange, not a bonded rubber seal. Any exposed connection that needs weather sealing must include an appropriate, specified sealing arrangement.
Product
Are other series sizes the same product configuration?
The broader gauge and length list describes the series. Each requested size, material, point and finish combination is checked separately; it is not a complete stock matrix.
OEM
Can you customise the head, drive and dimensions?
We can review head logos, head shapes, drive details, dimensions and tolerances against your drawing or specified ASME reference. The agreed design defines the production requirement.
OEM
Can you match a colour or surface treatment?
Head colour matching, passivation and specialty finishes can be reviewed for the selected material and application. Provide the colour reference and exposure conditions with your brief.
OEM
Are samples available before production?
Custom samples and initial inspection reports can be arranged before full production. The sample quantity, inspection scope and approval criteria are agreed during development.
Packaging
Which packing formats can we choose?
Small polybags, inner boxes and industrial bulk packing are available formats. Specify the quantity per pack and handling requirements so the packing specification can be agreed.
Packaging
Can inner and outer packs carry our brand?
Yes. Inner and outer box designs, printed logos and brand artwork can be prepared from your supplied files. Artwork and pack dimensions are reviewed before production.
Packaging
Can you include our barcodes and shipping marks?
Private labels, UPC / EAN barcodes, part numbers and shipping marks can be included in the packaging brief. Supply the required data and label layout for checking.
ORDER SUPPORT
Documents, Production & Delivery
Material & inspection records
Material test reports and mill certificates can be requested for the order. Agree the required documents, inspection scope and batch traceability against the selected material before production.
Stock & custom production
Available stock and factory production follow different order routes. Stock availability is checked for the requested configuration; bulk and custom orders are scheduled to the agreed specification and quantity. Timing is established in the quotation.
International shipping
FOB, CIF and DDP arrangements can be discussed for the destination. Shipment tracking supports the agreed transport route. Route availability, DDP coverage and delivery terms are established with the order.
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 |
Confirm the edition, component scope and inspection documents. ANSI needs a specific reference; ASTM F593 group references do not add 305 as a sale option or certify the complete screw.
