Value Collection SCXX204030-050BX M4 Hex Socket Cap Screw 50pk

Product Description

The VALUE COLLECTION SCXX204030-050BX is a partially threaded hex socket cap screw in M4 x 0.70 metric thread, with a 30 mm length under the head. Manufactured from 316 stainless steel to austenitic grade A4, this fastener resists corrosion in wet, chemical, and marine environments. The bright, uncoated finish maintains tight dimensional tolerances straight from the factory. Conforming to DIN 912, it is suited for precision mechanical assemblies where a recessed drive and reliable clamping load are required. Sold in a minimum order quantity of 50 pieces, it is commonly installed by millwrights, pipefitters, OEM assembly technicians, and maintenance professionals working in corrosion-prone environments.

This screw is used in light machinery, fluid handling equipment, enclosures, and structural assemblies where metric fastening and corrosion resistance are priorities. The hex socket drive allows installation in tight clearance areas where a wrench or open-ended tool cannot reach. The partial threading provides a smooth shank zone for applications requiring a controlled clamp length or shoulder-style fit. It is a practical choice for both new construction and maintenance-and-repair work in industrial, marine, and food-processing settings.

Key Features

• M4 x 0.70 metric thread with 30 mm length under head
• Partially threaded for shoulder-style clamping applications
• 316 stainless steel, austenitic grade A4 for high corrosion resistance
• Bright, uncoated finish with no dimensional buildup from plating
• Hex socket (Allen) drive for use in limited-clearance installations
• Conforms to DIN 912 fastener standard

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw, compatible with any M4 x 0.70 threaded hole or insert requiring a partially threaded cap screw in grade A4 stainless steel.

Installation Notes

Install using a properly sized hex key or Allen driver bit to avoid rounding the socket drive. Confirm the receiving thread is clean and free of debris before torquing. Power down or de-energize any equipment before fastener service when working on electrical enclosures or mechanical assemblies. Stainless fasteners in stainless housings should be installed with anti-galling compound to prevent thread seizure during tightening.
