#14 wood roofing design · Bonded EPDM washer
Stainless Steel #14 Hex Head Wood Roofing Screws with Serrated Thread
A larger #14 shank, deep wood threads and a Gimlet point form the timber fastening portion of this roofing screw. The hex flange head and pre-assembled EPDM washer provide controlled seating for corrugated roofing, siding and timber-framed buildings.
- #14 nominal outer diameter: 6.3 mm
- Heat-treated 410, 304 or 316 stainless steel
- Gimlet point and stainless steel / EPDM sealing washer
KEY FEATURES & PERFORMANCE
A firm timber fixing.
A controlled seal.
This design joins metal sheets to wood framing through a coarse, serrated wood thread. Its large-gauge shank and external hex drive support installation control; the bonded washer addresses the exposed sheet contact. Connection loads and sealing requirements are assessed together.
- 01
Material for the exposure
Heat-treated 410 offers a harder material option. 304 and 316 provide alternatives for corrosion requirements, with 316 considered for salt-exposed or chemically demanding conditions. Material and point combinations are specified individually.
- 02
Larger #14 shank
The nominal 6.3 mm outer diameter distinguishes this screw from the #10 design. It provides a larger fastening section, but diameter alone does not establish a shear or withdrawal rating.
- 03
Deep wood-thread engagement
Widely spaced, deep wood threads engage the timber support. The product is identified with serrated thread; the precise serration, thread length and penetration are defined by the selected drawing.
- 04
Sharp Gimlet entry
The Gimlet point starts the fixing at the sheet and timber interface. Sheet material, wood species and edge distance guide entry preparation and any pilot-hole requirement.
- 05
Pre-assembled EPDM seal
Vulcanized EPDM is bonded to a stainless steel backing disc. Correct compression forms the weather-sealing contact for rain and wind-driven moisture while allowing the specified assembly to accommodate movement.
- 06
Six-point socket engagement
The external hex accepts a matching nut setter for torque transfer and seating control. Correct socket fit and stopping position help protect the head, sheet and EPDM washer during installation.

APPLICATIONS & CONNECTION PLANNING
Connections & Selection Details
Corrugated roofing
The washer seats against the roof sheet while the thread engages timber framing or purlins. Use the sheet profile, lap thickness and fixing schedule to select length and seating position.
Siding, sheds & farm buildings
Wall siding, agricultural buildings and sheds are listed applications. Timber condition, exposed metal surfaces and moisture levels guide the material, coating and sealing requirements.
Residential timber framing
For roof and cladding connections over residential timber supports, consider wood species, edge distances and treatment. Required wind or withdrawal resistance must be supported by data for the actual connection.
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
Specify the Finish
with the Fixing
Ruspert is a listed coating option for this range. Match its availability and colour to the selected #14 configuration, support treatment and surrounding cladding materials.
Material grade and finish address different parts of the exposure requirement. Identify contact metals, coastal or industrial conditions and treated timber in the enquiry. Any coating test requirement is agreed for this product configuration; results from another roofing screw are not assumed.

Product, OEM & Packaging Q&A
Product selection, custom production and packing details for this screw design.
Product
Does the #14 diameter define a holding value?
It identifies the nominal outer diameter, not a rated connection capacity. Timber species, penetration, edge distance and the complete assembly determine which test or design data is needed.
Product
What makes the washer assembly weather-sealing?
A stainless steel backing disc supports bonded, vulcanized EPDM at the sheet surface. Performance depends on the selected washer, correct seating and controlled compression.
Product
Which details define the serrated wood thread?
The product name identifies a serrated thread, while the specification describes deep coarse wood threads and a Gimlet point. Use the agreed drawing to set the serration, thread length and point arrangement.
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.
