Value Collection 47509 M4x0.70 Hex Socket Cap Screw 50-pack

Product Description

The VALUE COLLECTION 47509 is a partially threaded hex socket cap screw in M4 x 0.70 metric thread with a 40 mm length under head. Manufactured from 18-8 austenitic stainless steel to material grade A2, it provides corrosion resistance suited to general industrial, mechanical, and light structural fastening applications. Drive engagement is via a hex socket, requiring an Allen key or hex bit driver for installation. Sold in a package quantity of 50 fasteners. Conforms to DIN 912 fastener standard, making it a dimensionally consistent choice for metric-specified assemblies.

This screw is appropriate for mechanical assemblies, equipment maintenance, panel attachment, and general-purpose metric fastening where corrosion resistance is a factor. The partially threaded shank allows for clamping applications where an unthreaded grip length under the head is required. Suitable for use by HVAC technicians, plumbers, electricians, pool equipment service pros, and general trade professionals working with metric-fastened components.

Installation Notes

Installation requires a correctly sized hex key or hex bit driver to prevent rounding of the socket drive. Ensure threaded receiving holes are clean and properly tapped to M4 x 0.70 before installation. Stainless steel fasteners are susceptible to galling during installation — apply an appropriate anti-seize compound if repeated removal is anticipated. Follow applicable equipment manufacturer torque guidance for the specific assembly.
