Value Collection A210288 Button Cap Screw M8x1.25 20mm 25pk

Product Description

The VALUE COLLECTION A210288 is a fully threaded button socket cap screw designed for metric fastening applications. Manufactured from 18-8 (A2) stainless steel with a bright, uncoated finish, this screw offers solid corrosion resistance in general industrial, mechanical, and light structural assemblies. The M8x1.25 thread size and 20mm length under head make it a common choice where a low-profile button head is required and clearance is limited. Drive engagement is through a 5mm hex socket. This package contains 25 pieces, suitable for shop stock or job-lot use by maintenance technicians, millwrights, and fabricators.

This fastener is suited for metric assembly work in manufacturing, equipment maintenance, and fabrication environments. The button head profile reduces snag risk in applications where a traditional hex cap head would protrude excessively. The right-hand thread and ISO 7380 standard construction make it compatible with standard metric tapped holes and insert hardware commonly found in machinery, enclosures, and structural brackets.

Key Features

• M8x1.25 metric thread, fully threaded along the 20mm under-head length
• Button head profile for low-profile, flush-style fastening
• 5mm hex socket drive for use with standard Allen keys or hex bit drivers
• 18-8 (A2) stainless steel construction for corrosion resistance in general service
• Bright, uncoated finish — no interference with tight tolerances
• Conforms to ISO 7380 fastener standard with 4G/6G thread fit class

Compatibility

Designed as an ISO 7380 metric button socket cap screw for use in standard M8x1.25 threaded holes in machinery, equipment enclosures, and fabricated assemblies.

Installation Notes

Installation is performed with a 5mm hex key or socket bit driver. Verify thread engagement depth and confirm the tapped hole is free of debris before driving. Avoid cross-threading by starting the fastener by hand to confirm thread alignment before applying torque. Stainless steel fasteners are susceptible to galling — use an appropriate anti-seize compound when assembling in high-friction or high-temperature conditions.
