Value Collection MP30576 Hex Head Cap Screw 1/4-20

Product Description

The VALUE COLLECTION MP30576 is a 1/4-20 UNC hex head cap screw designed for general fastening applications where corrosion resistance is critical. Manufactured from Grade 316 stainless steel with a bright uncoated finish, this fastener measures 1-3/4 inches under the head and features partial threading along the shank. Grade 316 stainless offers superior resistance to chlorides, saltwater, and many industrial chemicals compared to 304-series stainless, making it a reliable choice for wet, coastal, or chemically exposed environments. Installed using a standard hex drive or wrench, this screw is well suited for trade professionals working in demanding conditions.

This hex head cap screw is commonly used in HVAC, plumbing, electrical enclosure, and pool equipment applications where stainless hardware is required to prevent galvanic corrosion or rust in high-moisture settings. Partial threading provides a smooth shank section for applications requiring a bearing surface or precise joint clamping. Suitable for both residential and light commercial installations where inch-series UNC fasteners are specified.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in wet and chemical environments
• 1/4-20 UNC thread standard for compatibility with standard inch-series tapped holes and nuts
• 1-3/4 inch length under head with partial threading for solid shank clamping
• Bright uncoated finish — no risk of coating delamination in harsh conditions
• Hex head drive accepts standard wrenches and socket sets

Compatibility

Designed as an OEM-style replacement or standard fastener for applications requiring 1/4-20 UNC inch-series hex head cap screws in Grade 316 stainless steel.

Installation Notes

Installation is performed with a standard hex wrench or socket set sized for a 1/4-20 fastener. Ensure the mating tapped hole or nut is also rated for stainless or compatible materials to avoid galling, which is common with stainless threads — applying an anti-seize compound is standard practice. Power down or depressurize any system before replacing fasteners on live equipment. Follow applicable mechanical and structural codes for the specific trade application.
