Value Collection R80260421 Hex Head Cap Screw M20 X 2.50

Product Description

The VALUE COLLECTION R80260421 is a metric hex head cap screw designed for general-purpose mechanical fastening in applications that require corrosion resistance and dimensional accuracy. Manufactured from 18-8 stainless steel with no additional coating, this fastener delivers reliable performance in wet, outdoor, and chemically exposed environments. The M20 x 2.50 thread profile and 110 mm length under head make it suitable for medium-to-heavy structural connections. The partially threaded shank provides a smooth bearing surface for load-bearing joints where a fully threaded fastener would be inappropriate. Installation requires a 30 mm hex wrench or socket.

This screw is used in industrial maintenance, equipment assembly, structural fabrication, and mechanical installations where metric fasteners are specified. The 18-8 stainless steel grade is a common choice for food-processing environments, marine-adjacent applications, and outdoor assemblies where mild to moderate corrosion exposure is expected. Machinists, millwrights, maintenance technicians, and general contractors routinely specify this fastener type when metric thread engagement and corrosion resistance are both required.

Key Features

• M20 x 2.50 metric thread for precise engagement in tapped holes and with metric nuts
• 110 mm length under head provides adequate grip range for thick material stacks
• Partially threaded shank delivers a smooth shank section for shear-load and locating applications
• 18-8 stainless steel construction resists rust and oxidation without a surface coating
• Uncoated finish maintains true dimensional tolerances with no coating buildup on thread flanks
• 30 mm hex drive accommodates standard metric hex sockets and open-end wrenches

Compatibility

Designed for use with M20 x 2.50 metric-threaded nuts, washers, and tapped holes conforming to standard metric thread specifications.

Installation Notes

Installation is typically performed by machinists, maintenance technicians, or construction tradespeople using a 30 mm socket wrench or open-end wrench. Verify that mating threads are clean and free of debris before driving the fastener. When installing stainless steel fasteners, apply an appropriate anti-galling lubricant to the threads to prevent thread seizure during torquing. Follow applicable structural or equipment specifications for torque values, as none are specified by the manufacturer for this listing.
