Hillman Fasteners 190051 Zinc Plated Hex Bolts 100 Pack

Product Description

The HILLMAN FASTENERS 190051 is a 100-pack of zinc-plated Grade 2 hex bolts sized 0.25 inches in diameter by 4 inches in length. These machine bolts are engineered to adhere facing materials and resist shear movement across a range of structural and general-purpose fastening applications. The zinc plating provides corrosion resistance suitable for typical indoor and light outdoor use. Grade 2 classification makes these bolts appropriate for most general fastening tasks where high-strength hardware is not required. Each pack contains 100 bolts, making this a practical bulk option for contractors, tradespeople, and facilities maintenance crews who need consistent stock on hand.

These hex bolts are suited for wood-to-wood, wood-to-metal, and metal-to-metal connections in residential and light commercial construction, HVAC equipment mounting, plumbing support brackets, electrical panel framing, and general mechanical assembly. Their standard hex-head profile accepts common wrenches and sockets, making installation straightforward in most field conditions. The 0.25-inch diameter and 4-inch length combination is commonly used for through-bolting framing members, equipment bases, and structural brackets.

Key Features

• Grade 2 zinc-plated steel construction with corrosion resistance for typical use environments

Compatibility

Designed for general fastening use in wood-to-wood, wood-to-metal, and metal-to-metal applications. Use with Grade 2 or matching-grade washers and nuts for proper joint performance.

Installation Notes

Pre-drill all holes to the appropriate clearance diameter before installing these bolts. Always pair with washers and nuts of a similar grade and finish to avoid galvanic mismatch and ensure consistent clamp load. Use a properly sized wrench or socket to drive the hex head — do not use pliers or adjustable tools that may round the head. Follow applicable building codes and structural fastener requirements for the specific assembly type.
