Value Collection BHS7X04020-050BX M4x0.7 Button Cap Screw 50pk

Product Description

The VALUE COLLECTION BHS7X04020-050BX is a fully threaded button socket cap screw designed for metric fastening applications where a low-profile head and clean appearance are required. It features an M4x0.7 thread size with a 20 mm length under the head and a 2.50 mm hex socket drive. Constructed from A2 (18-8) stainless steel with a bright, uncoated finish, it offers reliable corrosion resistance in general-purpose and light industrial environments. The button head profile reduces surface stress and sits flush in countersunk or surface-mount applications. This screw conforms to ANSI/ASME B18.3.4M and ISO 7380 standards. Sold in a box of 50.

This fastener is suited for machine assembly, panel mounting, enclosure fabrication, and light structural connections where a smooth, rounded head is preferable to a standard hex cap or flat-head configuration. The metric M4x0.7 thread is commonly used in electronics enclosures, instrumentation, HVAC equipment panels, and light-duty machinery. The A2 stainless steel material grade is appropriate for indoor and moderately corrosive outdoor environments. Licensed trades and assembly technicians working on equipment that specifies ISO 7380 button head fasteners will find this screw a direct-standard-compliant option.

Key Features

• M4x0.7 metric thread with right-hand direction and 6G thread fit class per ISO 7380 and ANSI/ASME B18.3.4M
• Button head profile provides low-profile, smooth surface with reduced stress concentration
• 2.50 mm hex socket drive for use with standard metric Allen keys or hex bit drivers
• A2 (18-8) stainless steel construction for corrosion resistance in general and light industrial use
• Bright, uncoated finish — no plating to introduce dimensional variation on threaded engagement
• Fully threaded, 20 mm length under head — consistent engagement across the full shank

Compatibility

Designed as a standard-compliant replacement or stock fastener for any application calling for an ISO 7380 button socket cap screw in M4x0.7 metric thread size.

Installation Notes

Install using a calibrated 2.50 mm hex key or hex socket bit driver. Ensure mating threads are clean and free of debris before installation. Do not exceed the torque rating specified by the equipment manufacturer for M4 stainless fasteners, as A2 stainless steel is susceptible to galling if driven without appropriate lubrication or at excessive speed. Minimum order quantity for this SKU is 50 pieces.
