Value Collection D39448 Hex Head Cap Screw 5/8-18 X 1-3/4 in

Product Description

The VALUE COLLECTION D39448 is a fully threaded hex head cap screw manufactured from Grade 8 steel with a zinc yellow dichromate finish. It features a 5/8-18 UNF thread and measures 1-3/4 inches under the head. Grade 8 steel provides high tensile strength suited for demanding fastening applications, and the zinc yellow dichromate coating adds corrosion resistance while meeting common industrial finish requirements. This fastener conforms to ASME B18.2.1 dimensional standards. It is installed by maintenance technicians, millwrights, machinists, and general trade professionals wherever a high-strength inch-series fine-thread cap screw is required.

This hex head cap screw is used in industrial assembly, machinery maintenance, structural fastening, and equipment repair applications where a fine-thread, high-strength fastener is specified. The 5/8-18 UNF thread engagement and fully threaded body make it well suited for through-bolt and short-grip applications. The zinc yellow dichromate finish provides moderate corrosion protection appropriate for indoor and sheltered industrial environments.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 5/8-18 UNF fully threaded body for maximum thread engagement in short-grip installations
• Zinc yellow dichromate finish provides corrosion resistance and meets common industrial coating specifications
• Conforms to ASME B18.2.1 dimensional standards for consistent fitment and interchangeability
• Standard hex drive accepts common wrenches and impact sockets used in trade and industrial settings

Compatibility

Designed as a standard inch-series UNF hex head cap screw suitable for any application requiring a 5/8-18 Grade 8 fully threaded fastener conforming to ASME B18.2.1.

Installation Notes

Installation requires a standard hex wrench or socket sized for a 5/8-inch hex head cap screw. Verify mating thread condition and clean thread engagement before driving to prevent cross-threading. Do not exceed the rated load limits for Grade 8 fasteners in the intended joint. Follow applicable industry or equipment manufacturer torque specifications for the joint material and clamp load required.
