Hillman Fasteners 831518 Hex Head Cap Screw 1/4-20 X 2 in Ss 100pk

Product Description

The HILLMAN FASTENERS 831518 is a 100-pack of 1/4-20 x 2-inch hex head cap screws in 18-8 stainless steel with coarse thread. These fasteners are engineered for secure mechanical connections in applications where corrosion resistance is a priority. The 1/4-20 coarse thread pattern provides strong clamping force and resists cross-threading during installation. Stainless steel construction makes them well suited for outdoor, marine-adjacent, and high-moisture environments where carbon steel hardware would degrade. Electricians, plumbers, HVAC technicians, and general contractors routinely specify hex head cap screws of this size for equipment mounting, panel fastening, and structural connections.

These fasteners are appropriate for both residential and light commercial applications. Common use cases include securing electrical enclosures, mechanical equipment bases, pipe hangers, HVAC unit frames, and structural assemblies. The hex head drive style is compatible with standard hex wrenches and socket sets, making installation straightforward in tight or confined spaces where torque control is important. The 100-piece quantity per box suits service trucks and job-site supply kits where this size sees frequent use.

Key Features

• 1/4-20 coarse thread for reliable thread engagement and resistance to cross-threading
• 2-inch length suitable for medium-depth fastening applications
• Stainless steel construction provides corrosion resistance in wet or outdoor environments
• Hex head drive style compatible with standard sockets and wrenches
• 100-piece pack quantity reduces resupply frequency on active job sites

Compatibility

Designed as a standard 1/4-20 UNC hex head cap screw suitable for use wherever this thread size and length are specified in mechanical, electrical, or HVAC installations.

Installation Notes

Installation is performed by hand trade professionals using a socket wrench or hex driver sized for 1/4-inch hardware. Follow torque requirements specified in the applicable equipment manual or installation drawing. When fastening into aluminum or dissimilar metals, apply an appropriate anti-seize compound to reduce the risk of galvanic corrosion between mating surfaces. Always confirm thread engagement before applying final torque.
