Hillman Fasteners 190021 Hex Bolt 1/4-20 X 1-1/2 in 100 Pack

Product Description

The HILLMAN FASTENERS 190021 is a 100-pack of 1/4-20 x 1-1/2 inch hex bolts manufactured from low carbon steel with a coarse thread pattern. These are standard hex-drive fasteners suited for general mechanical assembly, structural bracketing, and equipment mounting applications. Each bolt features a coarse 1/4-20 thread pitch, which provides reliable engagement speed and resistance to cross-threading during installation. The pack quantity makes this a practical choice for contractors, maintenance technicians, and trade professionals who need consistent fastener stock on the job or in the shop.

These hex bolts are appropriate for a wide range of residential and light commercial applications where a 1/4-20 coarse thread fastener is specified. Common uses include HVAC equipment mounting, electrical panel bracketing, plumbing fixture attachment, and general mechanical assembly. The low carbon steel construction is suited for indoor or protected installations where corrosion exposure is limited. Sold in a box of 100 individual bolts, this pack supports high-volume fastening tasks without requiring frequent restocking.

Key Features

• 1/4-20 coarse thread pattern for fast engagement and broad compatibility with standard nuts and tapped holes
• 1-1/2 inch grip length suitable for typical light-duty structural and mechanical connections
• Low carbon steel construction provides adequate tensile strength for general trade applications
• 100-count pack reduces restocking frequency on active job sites
• Standard hex-drive head works with common wrenches and sockets

Compatibility

Designed as a standard 1/4-20 coarse thread hex bolt for use with any corresponding 1/4-20 nut, washer, or tapped hole conforming to ASME/ANSI inch fastener standards.

Installation Notes

Installation is performed with a standard hex wrench, open-end wrench, or socket driver sized for a 1/4-20 hex bolt head. Always confirm the mating nut or tapped hole thread specification matches 1/4-20 coarse before driving. Do not use these bolts in applications requiring corrosion-resistant or grade-rated fasteners without verifying suitability. Follow applicable code requirements, including NEC or IFGC guidelines, when fastening electrical or gas-related equipment.
