Head-Cracking Issues of 0.25 inch Hex Screw
I. Root Causes of Head Cracking
Cracking in the head of 0.25 inch Hex Screw generally falls into two categories—forging cracks and forging bursts—both evaluated under GB/T 5779.1.
Cracking in the head of 0.25 inch Hex Screw generally falls into two categories—forging cracks and forging bursts—both evaluated under GB/T 5779.1.
1. Forging cracks: they usually originate during the cutting or forging stage and are located on the top surface of the head or on the raised portion of recessed heads.
2. Forging bursts: these develop during forging and often appear at the corners of the hex head, on the flange periphery, around the circumference of round heads, or on the raised area of recessed heads of 0.25 inch Hex Screw.
II. Preventing Head Cracking in 0.25 inch Hex Screw
Cracking tends to occur in pan, cylindrical, and cross-recessed heads because they undergo greater deformation. High raw-material hardness or inclusions increase the risk.

Solutions:
• Customize each 0.25 inch Hex Screw order by selecting low-hardness, high-purity 304/316 stainless-steel wire.
• Optimize forging parameters for 0.25 inch Hex Screw to reduce cold-forging strain.
• For elevated requirements, supply 0.25 inch Hex Screw with 100 % visual inspection to eliminate defective parts.

III. Impact of Minor Head Cracks on Mechanical Performance of 0.25 inch Hex Screw
Extensive in-house testing shows that minor head cracks within GB/T 5779.1 limits do not impair the clamping force of 0.25 inch Hex Screw. Because the threaded section carries the load while the head only provides locking and positioning, the stressed area is small. Multiple batch tests confirm that 0.25 inch Hex Screw still meets all specified torque and tensile requirements, ensuring reliable use in general industrial environments.
