Value Collection IEH5425 Sex Bolt 5/16-18 Flat Head Phillips

Product Description

The VALUE COLLECTION IEH5425 is a stainless steel tamper-resistant sex bolt binding post designed for secure, flush-mount fastening applications. The flat head, Phillips drive barrel post accepts a mating screw to clamp two or more panels or materials together in a single through-bore. Constructed from Grade 18-8 stainless steel with an uncoated finish, it resists corrosion in wet or outdoor environments. The barrel measures 2.0625 inches in length with an overall assembly length of 1.5 inches. This fastener is sized to 5/16-18 UNC thread and weighs 0.01 pounds per unit.

Sex bolt binding posts are commonly used in construction, signage, leatherwork, book binding, and panel assembly where a through-bolt and nut configuration is impractical or where a clean, flush surface is required on both sides of the material. The 5/16-18 UNC thread sizing suits medium-duty clamping tasks. The tamper-resistant design discourages unauthorized disassembly, making it suitable for public-facing installations such as directories, menu boards, and access panels.

Key Features

• Grade 18-8 stainless steel construction provides corrosion resistance in damp or outdoor environments
• Flat head profile sits flush with the mounting surface for a clean finished appearance
• Phillips drive allows installation with standard screwdrivers or power tools
• Tamper-resistant design reduces risk of unauthorized removal
• 5/16-18 UNC thread standard ensures broad compatibility with mating screw barrels
• Uncoated finish — no plating to chip, flake, or introduce galvanic incompatibility

Compatibility

Designed as an OEM-style replacement or direct-use binding post for applications requiring a 5/16-18 UNC flat head sex bolt with a 2.0625-inch barrel length. Confirm barrel length and thread size match the material stack thickness before installation.

Installation Notes

Installation is performed by inserting the barrel post through a pre-drilled through-bore and threading the mating screw into the barrel from the opposite face. Verify hole diameter and stack thickness match the barrel dimensions before assembly. Use a Phillips screwdriver or appropriate bit — do not overtighten, as stainless steel fasteners are susceptible to galling. No specialized trade license is required, but follow applicable building or fixture codes for the end-use application.
