Marine Fasteners RP-825 Phillips Pan Head Machine Screw 1/4-20 x 1in 316 Stainless Steel 100-Pack

The Marine Fasteners RP-825 is a 1/4-20 x 1-inch Phillips pan head machine screw sold in a convenient 100-piece pack. Engineered for use in demanding marine, saltwater, and outdoor environments, these machine screws are manufactured from Type 316 stainless steel — the industry standard alloy for corrosion-resistant marine fasteners.

Key Features:

• Size: 1/4-20 thread x 1 inch length (fully threaded shank)
• Head Style: Pan head — low-profile dome shape for a clean, flush-friendly finish
• Drive Type: Phillips (cross-drive) for easy installation with standard #2 Phillips bit
• Material: Type 316 stainless steel with added molybdenum for superior resistance to chlorides, salt water, and corrosive environments
• Thread: 1/4-20 UNC (Unified National Coarse) — standard coarse thread for use with matching nuts or tapped holes
• Quantity: 100 pieces per pack — ideal for bulk marine projects and repairs

These screws are designed to thread into pre-tapped holes or be used with a matching 1/4-20 nut, making them suitable for a wide range of assembly, mounting, and repair applications on boats, docks, trailers, and other marine or coastal structures. The pan head profile distributes load evenly across the surface, reducing the risk of pull-through on softer materials. Sold in a 100-piece pack, the RP-825 provides excellent value for both professional marine tradespeople and DIY boaters.
