Value Collection 99006 Hex Head Cap Screw 1/4-20 Grade 8 100 Pack

Product Description

The VALUE COLLECTION 99006 is a 1/4-20 x 1.5 inch hex head cap screw manufactured from Grade 8 steel with an uncoated finish. It features a partially threaded shank and conforms to ASME B18.2.1 dimensional standards. The Unified National Coarse (UNC) thread form is the standard choice for general fastening in structural, mechanical, and equipment assembly applications. Grade 8 steel delivers high tensile strength, making this screw appropriate for joints that require clamping force beyond what lower-grade fasteners can provide. This package contains 100 pieces, suitable for stocking a shop or completing a production run.

This fastener is used across a wide range of trade and industrial applications including HVAC equipment mounting, mechanical equipment frames, pump and motor assemblies, and general structural fastening. The 1/4-20 UNC thread is one of the most common fastener sizes in North American equipment manufacturing. The partially threaded shank provides a shoulder bearing surface useful in applications where the fastener passes through an unthreaded clearance hole before engaging a threaded receiver.

Installation Notes

Installation is performed with a standard hex wrench or socket driver sized for a 1/4 inch hex head cap screw. Always verify thread engagement depth and confirm the mating thread or nut is rated for the load being applied. Do not mix Grade 8 fasteners with nuts or hardware of a lower grade rating in high-load joints. Refer to applicable mechanical or structural codes for torque and joint design requirements.
