Marine Fasteners RP-58 Hex Cap Screw 1/4-20 x 1-1/2 in Stainless Steel 50-Pack

The Marine Fasteners RP-58 is a 1/4"-20 x 1-1/2" hex cap screw engineered for demanding marine, coastal, and saltwater environments. Sold in a convenient 50-piece pack, these fasteners are built to resist the corrosion and degradation that standard hardware cannot withstand when exposed to moisture, salt air, and harsh weather conditions.

Key Features:

• Size: 1/4"-20 x 1-1/2" (coarse thread, UNC)
• Quantity: 50 pieces per pack
• Head Style: Hex cap (six-sided head for wrench or socket installation)
• Washer face under head for improved load distribution and a better seating surface
• Ideal for use with a nut or in a tapped hole
• Suitable for marine, boating, dock, and outdoor coastal applications

Hex cap screws feature a six-sided head designed for high-torque installation using a standard wrench or socket, providing a secure and reliable hold across a wide range of assembly applications. The washer-bearing surface under the head distributes clamping load evenly, reducing the risk of surface damage. Packaged in a 50-piece bulk pack, the RP-58 is a practical choice for boatbuilding, marine repair, dock construction, and any project requiring dependable corrosion-resistant fasteners.
