Hillman Fasteners 200087 Hex Cap Screw 5/16-18 X 2-1/2 in 100pk

Product Description

The HILLMAN FASTENERS 200087 is a Grade 5 hex cap screw designed for general structural and mechanical fastening in trade and industrial applications. This screw features a 5/16-18 coarse thread profile with a 2.5-inch length and is manufactured from heat treated steel, providing the tensile strength required for load-bearing connections. Sold in a 100-pack, this fastener is well suited for high-volume installation work where consistent grade-rated hardware is needed across a job. HVAC, plumbing, and electrical contractors commonly use Grade 5 hex cap screws when securing equipment bases, brackets, and structural supports.

This screw is appropriate for residential and light commercial applications where SAE Grade 5 strength is specified. Common install scenarios include securing equipment mounting pads, attaching structural steel brackets, and fastening mechanical components that require a reliable coarse-thread hex fastener. The 100-pack quantity supports bulk installation jobs and reduces the need for frequent reordering on larger projects. Heat treated steel construction makes this fastener suitable for indoor and sheltered mechanical environments.

Key Features

• Grade 5 heat treated steel construction for reliable tensile strength in structural fastening
• 5/16-18 coarse thread for fast engagement and strong pull-out resistance
• 2.5-inch length suits medium-depth through-bolting and equipment mounting applications
• Hex cap head drives with standard 1/2-inch wrench or socket for efficient installation
• 100-pack quantity reduces per-unit cost on high-volume jobs

Compatibility

Designed as a standard SAE Grade 5 hex cap screw for use in any application requiring a 5/16-18 coarse thread fastener with a 2.5-inch grip length in heat treated steel.

Installation Notes

Install using an appropriately sized wrench or socket driver rated for Grade 5 fastener torque requirements per the applicable mechanical or structural specification for the job. Ensure mating threads are clean and free of debris before installation. Do not substitute Grade 5 fasteners in applications requiring Grade 8 or higher-rated hardware. Follow all applicable mechanical and structural codes for the jurisdiction where the fasteners are being used.
