Value Collection HC3XX08040-025BX M8 Hex Cap Screw 316 Ss

Product Description

The VALUE COLLECTION HC3XX08040-025BX is a fully threaded hex head cap screw designed for applications requiring corrosion-resistant fastening. Manufactured from Grade 316 austenitic stainless steel to the A4 material designation, this fastener resists corrosion in marine, chemical, and food-processing environments. The screw follows the DIN 933 standard, features an M8 x 1.25 thread size, a 40 mm length under head, and a 13 mm hex drive. It arrives uncoated with a bright finish. This fastener is used by maintenance professionals, millwrights, and tradespeople working across industrial, marine, and commercial mechanical assemblies.

This screw is suited for metric fastening applications where corrosion resistance is a primary requirement. Typical installations include marine hardware, plumbing fixtures, chemical processing equipment, food-grade machinery, and outdoor structural connections. The fully threaded shank provides full thread engagement across the entire length under the head, making it appropriate for shorter clamping distances and through-bolt configurations. Minimum order quantity is 25 pieces per order.

Key Features

• Grade 316 austenitic stainless steel with A4 designation for superior corrosion resistance
• Fully threaded shank for maximum thread engagement across the clamping length
• DIN 933 standard compliance for dimensional consistency and interchangeability
• M8 x 1.25 metric thread size with 40 mm length under head
• 13 mm hex drive compatible with standard metric wrenches and sockets
• Bright uncoated finish — no plating to delaminate or interfere with torque values

Compatibility

Designed as a DIN 933-compliant M8 x 1.25 fully threaded hex head cap screw for use in any metric fastening application specifying Grade 316 or A4 stainless steel hardware.

Installation Notes

Installation is performed by qualified tradespeople using standard metric hand tools or power drivers with a 13 mm hex socket. Verify mating thread specification is M8 x 1.25 before installation to avoid cross-threading. Apply appropriate anti-seize compound if fastening stainless to stainless, as galling is common with austenitic grades under torque. Follow applicable fastener standards and equipment manufacturer torque guidelines for the assembly.
