Value Collection 88548706 1/4-20 X 1/2 in Hex Cap Screw 13pk

Product Description

The VALUE COLLECTION 88548706 is a 1/4-20 UNC hex head cap screw designed for general mechanical assembly and fastening applications. Measuring 1/2 inch under the head with partial threading, this fastener is manufactured from Grade 5 steel with a zinc-plated finish for basic corrosion resistance. The hex drive allows installation with standard wrenches or sockets. This package contains 13 screws, making it suitable for small batch repairs or dedicated single-job use. Plumbers, HVAC technicians, electricians, and general contractors reach for Grade 5 zinc-plated fasteners when securing brackets, panels, access doors, and equipment housings.

This screw is used across residential and light commercial trade work wherever a 1/4-20 UNC threaded connection is specified. Partial threading allows the unthreaded shank to bear shear loads and align mating parts before the threads engage. Common install scenarios include equipment mounting, sheet metal panel fastening, junction box hardware, and HVAC component bracket assembly. The 1/2-inch under-head length suits thin-to-medium stock thicknesses typical in mechanical and electrical enclosure work.

Key Features

• 1/4-20 UNC thread size for broad compatibility with standard inch-series tapped holes
• 1/2 inch length under head for use with thin and medium material stack-ups
• Grade 5 steel construction provides higher tensile strength than Grade 2 fasteners
• Zinc-plated finish offers basic corrosion resistance in dry and intermittently humid environments
• Partially threaded shank aids part alignment and handles shear loading
• Package of 13 screws minimizes leftover hardware for single-job installations

Compatibility

Designed for use in any application requiring a 1/4-20 UNC inch-series hex head cap screw with a 1/2-inch under-head length in Grade 5 steel.

Installation Notes

Install using a standard hex wrench, combination wrench, or socket driver sized for a 1/4-inch hex head fastener. Ensure mating threads are clean and free of debris before driving the screw. Do not overtighten, as Grade 5 fasteners in thin sheet metal can strip threads or distort the base material. Follow applicable mechanical and equipment codes when fastening structural or load-bearing assemblies.
