Value Collection 88548730 Hex Cap Screw 1/4-20 X 1-1/4 in Grade 5

Product Description

The VALUE COLLECTION 88548730 is a 1/4-20 x 1-1/4 inch hex head cap screw designed for general mechanical and structural fastening applications. Manufactured from Grade 5 steel with a zinc-plated finish, this screw delivers reliable clamping strength and basic corrosion resistance in a wide range of trade installations. The UNC (Unified National Coarse) thread form mates with standard tapped holes and nuts. Partially threaded along its shank, it provides a bearing surface that resists joint slippage under load. Each package contains 13 pieces with a minimum order quantity of 1 package, making it practical for small repairs and larger assembly jobs alike.

This fastener is used across residential and light commercial applications by HVAC technicians, plumbers, electricians, and general mechanical contractors. Common installation scenarios include equipment panel attachment, bracket and support fastening, electrical enclosure assembly, and mechanical equipment mounting where a 1/4-20 UNC threaded hole or nut is specified. The zinc plating provides mild corrosion resistance suitable for indoor and protected outdoor environments. Grade 5 steel meets SAE J429 strength requirements, making it appropriate for moderate-load fastening tasks encountered in day-to-day trade service work.

Key Features

• 1/4-20 UNC thread form for compatibility with standard tapped holes and hex nuts
• 1-1/4 inch length under head — partially threaded shank for improved joint bearing
• Grade 5 steel construction meets SAE J429 medium-strength requirements
• Zinc-plated finish provides basic corrosion protection for indoor and sheltered installations
• Sold in a 13-piece package, minimum order quantity of 1 package

Compatibility

Designed as a standard 1/4-20 UNC hex head cap screw suitable for use wherever a Grade 5 partially threaded fastener of this thread size and length is specified in mechanical, HVAC, plumbing, or electrical equipment assemblies.

Installation Notes

Installation is performed by hand or with a standard hex wrench or socket driver sized for a 1/4-20 fastener. Ensure the mating threaded hole or nut is clean and free of debris before driving. Do not overtighten — apply torque appropriate to Grade 5 steel fasteners at this thread size per the applicable mechanical standard or equipment manufacturer specification. Zinc-plated fasteners are not rated for submerged or high-humidity environments where stainless or hot-dip galvanized hardware would be required.
