Value Collection MSFI05006000-025BX Machine Screw 25pk

Product Description

The VALUE COLLECTION MSFI05006000-025BX is a 1/2-13 UNC machine screw with a flat head and slotted drive, measuring 6 inches in overall length. Manufactured from Grade 2 steel with a zinc-plated finish, this fastener is suited for general-purpose mechanical assembly where a flush or countersunk installation is required. The 1/2-13 thread designation indicates a half-inch nominal diameter with 13 threads per inch, conforming to Unified National Coarse (UNC) standards. This box contains 25 screws, making it appropriate for production runs, maintenance stock, or field repair kits used by mechanical contractors, millwrights, and general tradespeople.

These flat head slotted machine screws are used in a wide range of applications including equipment mounting, structural brackets, panel assemblies, and machinery maintenance. The flat head profile sits flush with or below the mating surface when installed in a properly countersunk hole, reducing protrusion in finished assemblies. The zinc plating provides a baseline level of corrosion resistance suited to indoor and light-duty outdoor environments. This screw is a standard inch-series fastener appropriate for use wherever 1/2-13 UNC thread engagement is specified.

Compatibility

Designed as a standard 1/2-13 UNC inch-series machine screw for use in any application requiring a flat head slotted fastener of this thread size and length.

Installation Notes

Installation requires a properly countersunk or flat-bottom clearance hole to seat the flat head flush with the mating surface. A calibrated torque wrench is recommended to avoid stripping the slotted drive or overstressing Grade 2 fasteners. De-energize and lock out any equipment before replacing or installing fasteners on powered machinery, in accordance with applicable OSHA lockout/tagout procedures. Do not substitute Grade 2 fasteners in applications that specify Grade 5 or Grade 8 hardware.
