Value Collection 99206 Hex Head Cap Screw 7/8-9 X 7 in Grade 8

Product Description

The VALUE COLLECTION 99206 is a Grade 8 steel hex head cap screw designed for high-strength fastening applications. It features a 7/8-9 UNC thread with a 7-inch length measured under the head, and partial threading along the shank. Manufactured to ASME B18.2.1 and SAE J429 standards, this fastener delivers the tensile and proof-load requirements expected from Grade 8 hardware. The uncoated finish makes it suitable for dry or controlled environments where additional corrosion protection is applied separately. Mechanical contractors, millwrights, and structural assemblers reach for Grade 8 hex cap screws when joint integrity under high stress or vibration is required.

This fastener is used in heavy-duty structural, mechanical, and industrial assembly applications. The partially threaded shank is well suited for joints where a smooth bearing surface under the head is needed to resist shear loads. Typical install scenarios include machinery mounting, steel-to-steel structural connections, and equipment anchoring in commercial and industrial settings. This screw ships in a package quantity of 5, which is convenient for low-volume repairs or specialty applications requiring only a handful of fasteners at a time.

Key Features

• Grade 8 steel construction meets SAE J429 tensile and proof-load requirements
• 7/8-9 UNC thread form for compatibility with standard inch-series tapped holes and nuts
• Partially threaded shank provides a smooth bearing section for shear-critical joints
• Conforms to ASME B18.2.1 dimensional standards for hex head cap screws
• Uncoated finish allows for field application of platings, coatings, or lubricants as required
• Packaged in quantities of 5, suitable for low-volume or service-repair use

Compatibility

Designed as a standard inch-series hex head cap screw for use with 7/8-9 UNC tapped holes and mating hex nuts in heavy-duty structural and mechanical assemblies.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with ASME and SAE fastener standards. Always confirm mating thread condition and hole alignment before driving the fastener. Torque to the value specified in the applicable engineering drawing or fastener-grade torque table for Grade 8 hardware. Never reuse a fastener that shows signs of galling, thread damage, or stretch.
