Item #: SCP-XXXX

Object Class: Safe

Special Containment Procedures: SCP-XXXX are to be kept in a small translucent acrylic box with interior dimensions of 30x30x30 centimeters. The box is to be 25 centimeters in thickness, with a lid for access to SCP-XXXX. The box is to be contained in the Safe wing. All personnel handling SCP-XXXX's box, whether for experimentation or for relocation, must wear thick gloves at all times during the handling process.

If subjects affected with SCP-XXXX die, the SCP-XXXX instances are to be immediately extracted from the body by the on-site surgical team, unless part of an ongoing experiment. If the surgical team is not available for immediate extraction of XXXX, any personnel on the scene are permitted to manually extract instances themselves, with small financial rewards as compensation for endangerment of bodily harm. Sightings of autonomous limbs around the Site are to be reported to the Head of Security and the head of the research team as soon as possible.

Description: SCP-XXXX is an assortment of screws of differing sizes between 1 mm and 15 cm in length numbering to -80- 65. When placed 3-20 centimeters away from an animal's joint12 for 1-3 minutes, SCP-XXXX will begin moving autonomously towards the joint, regardless of obstacles, and begin inserting itself into the subject. The anomaly does not produce anesthetic, so the procedure causes extreme pain for the host. When the instance is fully inserted into the body, the entry wound will heal without scarring, and the subject, now designated SCP-XXXX-1, will lose all feeling and control over the joint. At this point, it is impossible to remove the screw from the host without amputation and/or termination of the host.

How SCP-XXXX is inserted into the body depends on the joint it will attempt to take control of. For most types of synovial joints, SCP-XXXX will insert itself into the synovial cavity, and freely floats in the synovial fluid. How it is able to control the joint is unknown, but one theory is that it produces chemicals that interact with the nerves to induce motor function. Whereas, for temporomandibular joint, the screw will drill itself directly into the mandible and the temporal bone. There it will manually twist itself to control the movement of the jaw. Subject's jaws affected in this manner can only move on y-axis, due to the method of motion. The screw will take control of all joints below the joint it connected to (i.e. attaching to the elbow joint and being able to control the wrist and fingers, or attaching to the first cervical vertebra and controlling the entire body of the subject).

Immediately after insertion, the joint's movements will be exaggerated and disorganized, but over time the joint will develop more dexterity and strength, being proficient in fine-motor activities within 3-5 days. For example, SCP-XXXX instances placed in the lower spine will at first move the legs spastically and at random, and over time will become more coordinated in its movements, walking, jumping, even having the capability to run, dodge and leap over obstacles, with some being able to perform some simple self defense techniques.

The behavior of SCP-XXXX is apparently random. While it has been observed to follow orders from anyone other than its host, it usually acts of its own volition. Actions taken by SCP-XXXX can range from violent acts towards the host to passive acts such as knitting. It is noted that the behavior of SCP-XXXX is usually runs counter to what the host wants to do, and will try to prevent the host from finishing a task, by either a passive action, such as trying to walk away from an activity SCP-XXXX-1 was participating in, or a violent action, such as an arm affected by SCP-XXXX assaulting and killing the host to prevent them from solving a Rubick's Cube.

SCP-XXXX-1 are often negatively affected psychologically by the presence of SCP-XXXX, reporting feelings of depression, powerlessness, and fear of their own body. Many subjects often exhibit suicidal behavior/a tendency to self-harm, and attempt suicide at least once in the first six months. Subjects often request amputation of the affected limb, and have been known to attempt self-amputation.

If a limb SCP-XXXX is inhabiting is amputated, it still retains autonomy and mobility, being able to move by various unorthodox methods of locomotion. Whereas, if the subject is terminated without amputating the affected limb, the instance will be unable to control appendages. At this point, it is possible to unscrew the instance from the body, and recontain it or reuse it on other subjects. There is no known maximum of SCP-XXXX that can inhabit a single host, but they are not known to communicate or cooperate with each other, leading to several incidents wherein a D-class inhabited by multiple instances of SCP-XXXX-1 had to be physically restrained due to her limbs trying to attack one another.

Incident Log XXXX-005: During a relocation of SCP-XXXX, a security guard handled SCP-XXXX's containment using his bare hands, holding the box for an extended period of time. Four SCP-XXXX instances, all under 2 millimeters in length, drilled through the containment box, and inserted themselves into the security guard, possessing the first knuckle of the left thumb, the second knuckles of the ring finger and pinky of the left hand, and the third knuckle of the right index finger. The affected fingers were amputated, and the instances were extracted from the synovial fluid and placed back in containment. The affected guard was given 5 weeks paid leave and financial compensation. Prosthetic replacements were offered, and containment procedures were updated accordingly.
