Simpson #10 x 3/4" Pan Head 316 Stainless Steel Marine Screw by Simpson Strong-Tie is purpose-built for boat building and marine trade applications where corrosion protection is non-negotiable. Crafted from Type 316 stainless steel, this fastener resists saltwater, harsh chemicals, and the most demanding marine environments - making it the reliable choice for securing trim, rub rail, and molding to fiberglass boat hulls. Whether you are working with fiberglass, plywood, or wood-substitute materials, this marine-grade screw delivers a secure, lasting hold in conditions that would quickly degrade standard fasteners.

Key Features

• Type 316 Stainless Steel construction - provides the ultimate in corrosion resistance against saltwater, marine spray, and chemically caustic conditions, ensuring long-term fastener integrity in the harshest environments.
• High/Low Serrated Thread design - incorporates indentations that cut quickly and cleanly through high-density materials like fiberglass and wood composites, reducing driving effort and improving holding power.
• Extra-sharp point - speeds up screw starts during assembly, saving time and reducing the risk of surface damage when working on finished fiberglass boat hulls or plywood panels.
• #2 Phillips drive - works with standard Phillips drivers and bits for fast, efficient installation using common tools already on your worksite or boat shop.
• Pan head design with 0.365" head diameter - distributes clamping force evenly across the material surface, helping to secure trim, rub rail, and molding without pulling through or damaging the substrate.
• 3/4" length with 0.190" shank diameter - sized precisely for trim and finish applications on fiberglass hulls and thin composite panels where a shorter, fully threaded fastener is needed.

Why This Product

• When standard stainless steel screws fail in saltwater and chemical exposure, the Type 316 material grade in this fastener delivers the ultimate level of corrosion protection specifically required for marine and boat building trade applications.
• The high/low serrated thread form is engineered for fiberglass, plywood, and wood-substitute materials - the exact substrates used in boat hull trim and rub rail installation - giving you secure engagement where conventional threads may strip or slip.
• The sharp point and pan head combination makes this fastener ideal for applying molding and trim to curved or finished fiberglass surfaces without pre-drilling or surface damage, speeding up production in marine fabrication settings.
• Available in a flat head style as well, this screw family offers flexibility for different marine finishing applications while keeping the same proven corrosion-resistant 316 stainless steel construction throughout the line.

Frequently Asked Questions

What makes Type 316 stainless steel the right choice for marine fasteners?

Type 316 stainless steel is specifically formulated to withstand the most aggressive corrosion environments, including saltwater exposure and contact with harsh chemicals. This material grade provides the ultimate in corrosion protection for boat building and marine trade applications where standard steel or lower-grade stainless fasteners would corrode and fail prematurely.

What materials can this screw fasten into?

This marine screw is designed to fasten securely into fiberglass, plywood, and wood-substitute materials. The high/low serrated thread form is engineered to cut quickly and efficiently through high-density materials like these, making it well suited for trim, rub rail, and molding installation on fiberglass boat hulls.

Is this screw fully threaded along its entire shank?

Yes. Screws up to 1" in length - including this 3/4" screw - are fully threaded, providing maximum thread engagement and holding power throughout the entire shank length when fastening into fiberglass, plywood, or wood-substitute panels.

Is the pan head the only head style available in this marine screw line?

No. According to Simpson Strong-Tie, these stainless steel marine screws also come in a flat head style, offering flexibility depending on your specific marine finishing or trim application requirements.
